Application for determination of pH volumetric titration monopróticas acids and bases and dipróticas. The application is able to establish a titration graph acid / base and also to calculate the pH titrant volume or as the user requires. Features of three modules: titration weak acid based strong monoprotic. Titration weak base with a strong monoprotic acid. Titration fraction diprotic acid with strong base. The application initially determines fixed certain pH range and a chart. The user may determine the pH by adding a titration volume of titrant any value and can also calculate the volume of a basic titrant acid value or choosing a particular pH. Very useful in quantitative analytical chemistry.
