"Web1 dag geleden · On the reaction of HCl with water, HCl completely breaks down to release hydronium and chloride ions. Cl- is the conjugate base. A strong acid leads to the formation of a weak conjugate base. It is believed that the weaker the conjugate base is, the stronger is the acid. For strong acids, the value of pKa is less than -1.74. For HCl, pKa is -6.3. " - Keq of hcl
