Sodium hydroxide, potassium hydroxide, and ammonium hydroxide can be used to alkalize the permanganate solution, while a variety of reducing agents can be used, sugars being common. [ 1 ] [ 5 ] [ 8 ] A similar demonstration involves soaking paper in alkalized permanganate solution, which produces the same color changes as the paper is oxidized ...

This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
The vanishing valentine experiment is another chemical reaction related to the blue bottle experiment. This reaction occurs when water, glucose, sodium hydroxide, and resazurin is mixed in a flask. When the solution is shaken, it turns from light blue to a reddish color. The solution turns back to a light blue after being left to stand for a while.

Depending on their locations one could e.g. run an experiment at 5 and 10g in the same run. Each gondola can hold an experiment of a maximum 80 kilograms (180 lb). Experiments performed in this facility ranged from zebra fish, metal alloys, plasma, [ 21 ] cells, [ 22 ] liquids, Planaria, [ 23 ] Drosophila [ 24 ] or plants.
Description: Discusses structure and stereochemistry of synthetic polymers, polymerization kinetics, behaviour of polymers in solution, chain dimensions. Importance: First major text on polymer chemistry; presents both organic and physical chemistry aspects. Written by a chemist who made major contributions to the physical chemistry of polymers ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
