WebAmines react with HC l to form amine salts, such as ethylammonium chloride. C2H5NH2 + HCl → C2H5NH3+Cl-. base acid salt. Like ammonium salts, amine salts are soluble ionic compounds, so when the alkyl group is small they are water soluble but become less so as the carbon chain increases. We can show the reaction in Brønsted-Lowry terms ...
