But because HCl is a strong acid, the Cl– ion is not basic in solution, and it isn’t capable of deprotonating water.

Salts with acidic protons in the cation are most commonly ammonium salts, or organic compounds that contain a protonated amine group. .

This is due either to the presence of a metal cation that acts as a Lewis acid (which will be discussed in a later concept), or, quite commonly, due to a hydrolyzable proton in the cation or the anion. CopyCopied, InChI=1S/C6H7N.ClH/c7-6-4-2-1-3-5-6;/h1-5H,7H2;1H Acid salts are the converse of basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. 0000003535 00000 n Some salts, such as ammonium bicarbonate (NH4HCO3), contain cations and anions that can both undergo hydrolysis.
