Explain why alum crystals have to be washed with a 50:50 mixture of ethanol and water. Why does NH_3 have a lower boiling point than H_2O? Why is bromination more selective than chlorination? Why is ^{69}Se unstable? Why should organic solvents not be poured into sinks?

Chlorine treatment alters the normal rate of starch gelatinization in flour, slowing it in a way that improves gas retention. This allows the batter more time to rise, resulting in super-lofty, fine-grained cakes. Doubling down on that effect, chlorination alsoraises the temperature of protein ...

Ethanol made by fermentation is of low purity and hence needs to be purified, before it can be beneficial. In addition, denatured alcohol is toxic to drink and may be unsuitable for useful purposes. The product contains a high proportion of water and is distilled to produce a 95% (w/...
