The ChemDigiT application was designed to be 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 Newtonâ€“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
Trace titration curve and find pH and volume of titrant added at equivalent points of any combination of strong/weak acid-base
Balance chemical equations (max 8 reagents and 8 products). If Weight or mole of one specie is entered, amounts of all reagents and products will be calculated. If more than one value is entered, then ChemDigiT checks if there is a limiting reagent. If so this value is used for the stoichiometric calculation.
Calculate and convert concentration (molarity, molality, percent concentrations and molar fractions). All calculations will automatically take solution density into account. Built-in editable database of over 300 compounds with density tables
Calculator for dilution and solution mixing calculations.
Calculate A) buffer composition (acid and conjugated base concentration) or B) desired pH and total concentration. ChemDigiT doesnt use Henderson-Hasselbach equation, but exactly solves a sixth degree equation. Ionic Strength option to consider activities. Davies equation parameters editable. Calculate new pH after addition of strong acid/base.
Calculate solubility, pH and Ionic Strength of any solution of poorly soluble strong electrolyte. Built-in editable database of over 120 compounds with Solubility Product Constants. Evaluate effects of Hydrolysis (Anion), pH and Ionic Strength on the Solubility
