Drug use is the litmus paper not only for how a society wants to feel but how it deals with transgression.

"What we need is some kind of litmus paper than turns red when it's near a Communist," one officer half-jokingly told a journalist.

It appears to be a complex bit of kit, but Dr Suslick is quick to point out that the method is really not much different to a multidimensional form of litmus paper.

Some of my favorites that didn't make the cut were LUNG POWER, LINKIN PARK (we miss you, Chester Bennington), LATERAL PASS, LITMUS PAPER, LANDING PARTY, LIBRARY PASTE, LOTUS POSITION, LACROSSE PLAYER and LEARNER'S PERMIT.

Several other women have shared with me their stories of random manual inspections of breast milk and formula, including gloved hands, swabs, and litmus paper—unsettling to any parent who spends hours sterilizing bottles and pump parts to avoid contamination.

Litmus paper after being used The main use of litmus is to test whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at . Neutral litmus paper is purple.Manfred Neupert: Lackmus in Römpp Lexikon Chemie (German), January 31, 2013.

Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions, the solution is red, and under alkaline conditions, the solution is blue. Wet litmus paper can also be used to test for water-soluble gases that affect acidity or basicity; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, turns red litmus paper blue.

|
Chemical reactions other than acid–base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus dye is bleached, because of presence of hypochlorite ions. This reaction is irreversible, so the litmus is not acting as an indicator in this situation.

Due to a color change from blue to red at pH 3.0–5.2, Congo red can be used as a pH indicator. Since this color change is an approximate inverse of that of litmus, it can be used with litmus paper in a simple parlor trick: add a drop or two of Congo red to both an acid solution and a base solution. Dipping red litmus paper in the red solution will turn it blue, while dipping blue litmus paper in the blue solution will turn it red. This property gives Congo red a metachromatic property as a dye, both in strongly acidic solutions and with strongly acidophilic tissue.

Specifically, notable examples include both paper used for the regular purpose of printing, and the more specialized case of litmus paper, which in itself is used to characterize acidity and basicity.

Red litmus contains a weak diprotic acid. When it is exposed to a basic compound, the hydrogen ions react with the added base. The conjugate base formed from the litmus acid has a blue color, so the wet red litmus paper turns blue in alkaline solution.

But that doesn't bother me. I don't demand that a theory correspond to reality because I don't know what it is. Reality is not a quality you can test with litmus paper. All I'm concerned with is that the theory should predict the results of measurements.

Chemical eye injury may result when an acidic or alkaline substance gets in the eye. Alkali burns are typically worse than acidic burns. Mild burns produce conjunctivitis, while more severe burns may cause the cornea to turn white. Litmus paper may be used to test for chemical causes.

They are slippery to the touch, can taste bitter and change the color of pH indicators (e.g., turn red litmus paper blue). In water, by altering the autoionization equilibrium, bases yield solutions in which the hydrogen ion activity is lower than it is in pure water, i.e., the water has a pH higher than 7.0 at standard conditions.

Paper has been used in analytical chemistry as far back as the 1800s, when litmus paper was first reported, and has since been used for techniques such as paper chromatography and lateral flow assays. However, it was only identified as a material for microfluidic assays in 2007, when patterned paper was proposed as a low-cost platform for bioassays.

The flowers on the wall were red litmus paper which the ammonia – as an alkaloid – in the true smelling salts turned blue. Nurse Copling, who was Zarida in disguise, was the killer, in the hopes (which did not come to pass) of marrying the widower Pritchard. Sir Henry confirms that Nurse Copling was recently arrested for a similar murder.

In 1929 Alex passed the Leaving Certificate with honours in Mathematics and Chemistry. An exhibition took him to the University of Sydney, where he enrolled in science. He was drawn to this area due to chemical experiments he undertook while at school. > I can trace my interest in chemistry to my first chemical experiment in > school, changing the colour of litmus paper.

Chemical eye injury are due to either an acidic or alkali substance getting in the eye. Alkalis are typically worse than acidic burns. Mild burns will produce conjunctivitis while more severe burns may cause the cornea to turn white. Litmus paper is an easy way to rule out the diagnosis by verifying that the pH is within the normal range of 7.0—7.2.

District of Nowa Huta, built as a satellite industrial town by the communist government, always used to evoke strong emotions. Planned as a huge centre of heavy industry, Nowa Huta was to become also an ideal town for the communist propaganda. It was the litmus paper of political and social climate in Poland. The inhabitants of Nowa Huta were strongly affected by its history up to the end of communism.

Dyar recorded the sparks generated by the electrical current of his telegraph on a ribbon of moistened litmus paperDepew, p. 126. on a spool that revolved mechanically by a clockwork apparatus. The nitric acid that was formed on the litmus paper by the action of the electricity left appropriate legible small red marks for designated letters. Dyar's method was of frictional electrolytic nature where Morse's was an electromagnetic usage.

The reliable method is to aspirate some fluid from the tube with a syringe. This fluid is then tested with pH paper (note not litmus paper) to determine the acidity of the fluid. If the pH is 4 or below then the tube is in the correct position. If this is not possible then correct verification of tube position is obtained with an X-ray of the chest/abdomen.

The Chameleon sensors function similarly to litmus paper. The cassettes that hold the sensors are mounted onto the armband, and can be easily removed. The cassettes have a small viewing window that shows a uniform colored surface when not exposed to its particular trigger. Once exposed to it, half of the viewing window will change color, presenting a contrast that allows users to recognize that a threat is present.

Inks which are developed by a chemical reaction may depend on an acid-base reaction (like litmus paper), reactions similar to the blueprint process, or any of hundreds of others. Developer fluids may be applied using a spray bottle, but some developers are in the form of vapor, e.g. ammonia fumes used to develop phenolphthalein ink. There are also toy invisible ink pens which have two tips—one tip for invisible ink writing, and another tip for developing the ink.

Lyrically, the song is reminiscent of other Lennon output from that era, such as "Tomorrow Never Knows" and "She Said She Said", although Harrison has also been mentioned as its possible songwriter.Unterberger 2006, pp. 359–360. Indeed, on the bootleg "Day Tripping," the song is attributed to Harrison (with possible involvement from Donovan, Mike Love, and others) and given the name "Pink Litmus Shirt," a reference to spurious Beatles song "Pink Litmus Paper Shirt." The song utilises recording techniques that were also used in the Beatles' studio work.

If the state law is merely procedural, or relating merely to the form and mode of judicial operations, then the federal court does not have to apply the conflicting state law. However, the substance-procedure distinction is a generality as the Court rejected any test based upon "litmus paper criterion." Thus, a choice between state and federal law must be made with reference to the underlying policy of the Erie decision. The Court announced a modification of the "outcome- determinative" test in York, whereby the test must be applied in light of the twin aims of Erie, which are the discouragement of forum-shopping and avoidance of inequitable administration of the laws.

Lucy Moore, former friend of the late London bookstore owner Claire de Rouen, selected Templeton's book Litmus Test (Super Labo) for a tribute to de Rouen that was featured by the Modern Matter magazine in March 2013. In regard to Templeton's photographic exploration of Russia, Moore explains: "Like litmus paper turning irreversibly red after it has been soaked in lemon juice, the photographs document the way that first impressions leave indelible marks upon our memory, shaping what follows." Moore also writes that Templeton's skateboarding may be responsible for the collection's "feeling of equivalence between photographer and subject." Templeton explained in an April 2013 interview that the Leica M6 camera (with 50 mm lens) is the camera that he primarily uses for his photographic work, but that he also likes to use the Fuji GF670.

303 (1992) Critics of his earlier "clear-and-present-danger" opinion have insisted that the Abrams dissent stands on a different footing, and is more protective. The objection may be based in part on a misunderstanding. In his Abrams dissent, Holmes first disposed of the argument that the facts in the case supported a conviction under the clear-and-present-danger standard, insisting that a criminal prosecution required proof of specific intent to commit the crime that was charged. He then went on to say, however, that even if the defendants' speech could be punished as an attempted crime, even if "enough can be squeezed from these poor and puny anonymities to turn the color of legal litmus paper," the sentences of ten and twenty years, followed by deportation, showed that Abrams and his friends were prosecuted, not for their dangerous attempts, but for their beliefs.
