pH of Salt of Weak Acid and Strong Base Calculator

This Calctown Calculator calculates the pH of a salt of a weak acid and a strong base.

The default value of Kw is taken to be 10^-14 at 25⁰C;

C(concentration)

mol/dm³

a(disassociation constant)

H⁺(hydrogen ion concentration)

mol/dm³

A^- is conjugate base of weak acid

B⁺ is conjugate acid of strong base

K_w is ionic product of water

C is concentration of salt

a is disassociation constant

H⁺ is hydrogen ion concentration
