Virtual Titration Laboratory

The software is designed to emulate potentiometric titration in the Online mode. Virtual Titration allows to conduct laboratory work on analytical chemistry in virtual mode via the Internet. This allows to learn more about different types of titration in a relatively short time and reduce spending on equipment and reagents. The complex software simulates real laboratory work – students drop by drop add a standardized solution of alkali to a solution of acid of unknown concentration. At the same time, a graph on the dependence of pH of the titrated solution on the volume of the added titrant appears on the screen. Analyzing the graph, students should determine the concentration of titrated acid, then the software checks the accuracy of the calculation and informs the students on the mistake in their calculation.

Calculation of the Solubility of Slightly Soluble Salts of Weak Acids Depending on the Solution pH Level

The software is used to calculate the solubility of slightly soluble residuals of salts of weak acids in solutions of a strong acid. The software comprises two software packages: the first is responsible for the software- user interaction, and the second – for the actual calculation. The software contains two auxiliary user functions that provide solubility calculations depending on the experimental conditions. The software provides convenient input of initial data and output of results.
