Chemistry Utilities is a mac application, comprising of the numerous educational and scientific calculators:

Acid Base pH is the ultimate tool for accurate estimation of pH values of acid – base aqueous systems, particularly solutions of weak, strong, monoprotic and polyprotic acids and bases. Additionally It builds titration curves, provides pH and titrant volume values at equivalent points, helps with indicators and calculates titrant volume based on provided pH.

Chemical Equilibrium is a tool for accurate estimation of concentrations and pressures of a chemical reaction reactants and products at equilibrium. The app derives final, equilibrium parameters based on equilibrium constants (Kc and Kp), initial concentrations and stoichiometric coefficients. Additionally, app calculates reaction quotient for any given concentrations and stoichiometry. 

Chemical Kinetics app analytically solves chemical reaction rate equations and provides graphical representation of reagent and product concentration changes with time.  Additionally, app calculates half-life times and equilibrium constants, where it is appropriate.
 
Chemical Solution helps in preparation of simple chemical solution by dissolution of solid solute and in finding of moles, Molar masses and required weights of compounds. 

Solubility Products is a tool for accurate estimation of concentrations of solutes upon dissolution of solid compounds of low solubility. The tool is applicable to various chemical equilibrium tasks, such as salt dissociation to electrolytes, common-ion effect, separation by sedimentation and precipitation titration.  Application derives final, equilibrium concentrations of solutes based on equilibrium constant (Ksp), initial concentrations, solubility and stoichiometric coefficients. Additionally, app calculates reaction quotient for any given concentrations and stoichiometry.
