BATE-pH calculator 1.0.0.30

pH calculator is designed to help you in time consuming calculations that you may encounter in your daily practice. Consider the calculation of pH of solution containing phosphoric acid and ammonia:
It only takes seconds to find out pH - but thats not all!

Find - using pH calculator - exact pH of any mixture of strong/weak/polyprotic acid and base. Such mixtures include solutions of most salts and buffers.
Calculate, ignore, or force ionic strength during pH calculation.
Let pH calculator calculate concentrations (or activities) of all forms of dissociated acid and base present in the solution.
Use built into pH calculator expandable acid and base database.
Calculate the concentration of acids and bases using the simple concentration calculator.
Define solution constitution in several easy ways.
Use pH calculator to calculate the shape of virtually any acid/base titration curve.
Let pH calculator print calculation results and titration curves for further reference.
You will find the description of algorithm used for pH calculations in the pH calculation method section. Basically its a brute force numerical attack on a full set of equations describing acid and base dissociation equlibrium.

BATE pH calculator needs any PC class computer with properly running Windows - any version published after 1995 should do.

pH calculations are one of the first things taught in any general chemistry course. There are two reasons - first, pH is a very important property of the solution. Secondly, pH calculations are a very good introduction to the concept of chemical equilibrium in the solution. Whilst in many cases pH calculations are not very difficult thanks to the approximations that can be performed. Quite often we dont know how good these approximations are, or how good is pH value calculated with their use. Lack of reasonable method of pH calculation in case of acid with similar Ka values resulted in frustration.
