ChemDigiT is a chemical calculator. No approximations made. All calculated variables show their exact values. The algorithm used for calculations is based on a full set of equations describing acid/base and salt dissociation equlibrium solved with Newton–Raphson method.

* pH Acid-Base Section *

Find exact pH and equilibrium concentrations of all dissociated and undissociated species of any solution of strong/weak/polyprotic acid and base. Built-in database of over 60 weak acids and bases with pka and pkb editable tables

* pH Hydrolysis Section *

Find exact pH and equilibrium concentrations of all dissociated and undissociated species of any solution of salt.

* pH Mixtures Section *

Find exact pH and equilibrium concentrations of all dissociated and undissociated species of any mixture of two acids or two bases
