Calculate Kb for a base.
For a weak acid, Base Dissociation estimates the hydrogen-ion concentration from the dissociation constant and the acid's concentration, then converts it to pH. pH is a logarithmic scale, so each whole unit is a tenfold change in hydrogen-ion concentration.
Base Dissociation
pH = -log10[H+], with [H+] = sqrt(Ka.C)

This calculator takes 3 inputs: Acid concentration, Acid dissociation constant, Temperature. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
