1. Calculate (a) (b) the pH when 15 mL of 0.25 M HClO4 are added to 25 mL of 0.20 M NaOH. the pH when 25.0 mL of 0.40 M HCl are added to 40.0 mL of 0.30 M NH3. (Dissociation constant for ammonia is 1.8 x 10-5) (c) the pH when 50.0 mL of 0.25 M NaOH are added to 40.0 mL of 0.20 M HF. (Dissociation constant for hydrofluoric acid is 7.1 x 104) 1.
