WebbI dag · 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. WebbCalculate the change in pH when 8.00 mL of 0.100 M HCl (aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3 (aq) and 0.100 M in NH4Cl (aq).
