Making Esters From Alcohols
Making esters from carboxylic acids and alcohols. Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid. Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones containing a benzene ring).

Sulfuric Acid & Chlorine Bleach Reaction | Sciencing
Updated March 13, 2018. By Emily Jacobson. Chlorine bleach is a solution of sodium hypochlorite and water. Chlorine gas is produced when sulfuric acid is mixed with chlorine bleach. This reaction is a function of the change in pH of the solution from alkaline to acidic combined with the strong oxidant properties of hypochlorous acid.

Redox Reactions Involving Halide Ions and Sulfuric acid
Concentrated Sulfuric acid Acting as an Acid. The concentrated sulfuric acid gives a hydrogen ion to the halide ion to produce a hydrogen halide. Because this is a gas, it immediately escapes from the system. If the hydrogen halide is exposed to moist air, you see it as steamy fumes. As an example, concentrated sulfuric acid reacts with solid ...
