WebThe concentration of hydrochloric acid can be increased by adding more hydrochloric acid. When this happens, the equilibrium position moves to the left, away from HCl(aq) in the … WebEsters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a larger molecule whilst eliminating a small molecule. During esterification this small molecule is water. Esters have characteristic smells and are insoluble in water.
