BATE pH calculator
$40.00 - BPP Marcin Borkowski
BATE calculates pH of solutions containing mixtures of acid and base with up to 4 dissociation steps and titration curves for these acids and bases. Ionic strentgh can be calculated, omitted or forced. Program contains editable database of common weak acids and bases and accepts acid and base dissociation constants and protonation constants as input. Built in calculator allows easy calculation of molar masses and concentrations for given formula.
