Litmus test (politics) Litmus test (politics) A litmus test is a question asked of a potential candidate for high office, the answer to which would determine whether the nominating official would proceed with the appointment or nomination. The expression is a metaphor based on the litmus test in chemistry, in which one is able to test the general acidity of a substance, but not its exact pH. Those who must approve a nominee, such as a justice of the Supreme Court of the United States, may also be said to apply a litmus test to determine whether the nominee will receive their vote.
Alkalinity no strong acids or bases at this point. Therefore, the alkalinity is modeled and quantified with respect to the CO equivalence point. Because the alkalinity is measured with respect to the CO equivalence point, the dissolution of CO, although it adds acid and dissolved inorganic carbon, does not change the alkalinity. In natural conditions, the dissolution of basic rocks and addition of ammonia [NH] or organic amines leads to the addition of base to natural waters at the CO equivalence point. The dissolved base in water increases the pH and titrates an equivalent amount of CO to bicarbonate ion and
