Application for determination of pH volumetric titration monopróticas and dipróticas acids and bases. The application is able to establish a titration chart acid / base and also to calculate the pH titrant or volume as the user requires. It features three modules: titration weak acid based strong monoprotic. Titration weak base with a strong acid monoprotic. Diprotic titration weak 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 certain pH value. Very useful in quantitative analytical chemistry.
