Titration of Triprotic Acid

Neutralization titration is an analytical technique for estimation of concentration and strength of analyte acid or base. The known and calibrated, strong (undergoes complete dissociation) titrant solution is added in a drop wise manner to the unknown, analysed solution to build a pH – titrant volume plot – titration curve.

All the theoretical aspects presented below have been successfully implemented in “Acid Base pH” application available on Play StoreApple Store for iOS  and for Mac.

Half Life Time

Half Life Time, λ is a scientific concept defining time required for a quantity to reduce its value by half. The term is widely used in nuclear physics for description of radioactive decay and in biological medicine to analyse the drugs pharmacologic activity decay.  Actual approach to determine the λ value depends on type of process responsible for the change in an analysed quantity. Thus, λ remains constant during exponential decay (first order process), but diminishes with each step of zero order process and grows with each step of second order process.

Chemistry Utilities 2 for Mac

Chemistry Utilities 2 is a scientific and educational  application, available on Apple Store and designed for Apple Mac notebook and desktop platforms. It includes the following utilities:

Stoichiometry is a tool for parameterisation of chemical reactions. The application balances chemical reactions, derives molar masses, moles and actual masses of reactants and products based on their chemical formulas, stoichiometric coefficients and any quantitative data provided. Thus, it is enough to provide initial or final (after reaction accomplishment) mass or moles of one of the reaction component, to calculate all required and obtained masses and moles of all components. If data is available for several components, then limiting reagent will be found based on reaction stoichiometry.
