ChemBuddy Suite - all four calculators!

Every chemist occasionally needs to perform some basic calculations, such as converting concentrations, determining pH, figuring out the composition of a buffer, or solving a stoichiometric problem. These exercises are a waste of time when the problems are simple. When calculations are more complex, they frequently become impossible to complete on paper. This is especially true for pH calculations involving many dissociation equilibria. Software for general chemistry can help you avoid unnecessary time and stress at this point.

All of our chemical calculators are made to support routine procedures carried out regularly in laboratories across the world. Chemical calculators will save you time and reduce the possibility of error whether you are a professional or an amateur, a teacher or a student, a PhD or a technician.

If you work in an industrial or R&D lab you may concentrate on the real problems, instead of losing time for the preparatory tasks.

If you are a general chemistry teacher you may prepare individual questions for your students, by simply playing with substance amounts and immediately knowing the correct answers.

If you are a student you will save tens of hours every year using calculators for the tedious parts of the lab reports.

And that's not all - our general chemistry software can calculate dilutions, titration curves, endpoints pH, calculate ionic strength of the solution, activity coefficients and so on.

Check out Buffer Maker - buffer calculator, CASC - Concentration and Solution Calculator, BATE - Base Acid Titration and Equilibria and EBAS - Equation Balancing and Stoichiometry calculator. To read more about these chemical calculators select them on the right menu to browse through examples, screen shots and other information.

Please visit our sister site if you are interested in the history, measurements, and the theory behind pH. Please visit for information about titration techniques, curves and results calculation, end point detection, methods and so on. Finally, is a site where we try to post information about refractometers and refractometry as used in chemistry.
