Carboxylic acids can undergo reduction reactions. Reduction is the opposite of oxidation. For example, ethanoic acid (CH 3 COOH) can be formed by the oxidation of ethanol as shown below.

A solution with a pH value which is less than 7 is acidic. The acids which react with metals usually have quite a low pH, of either 3 or less. Some metals react with acids and when they do the ...

Esters are usually synthesized from an alcohol and an acid, most frequently, a carboxylic acid ... vinyl acetate now is produced via the vapor-phase reaction of ethylene and acetic acid over a ...
