Resumo
A method is considered for determining concentrations of components in solutions of two electrolytes with one common ion. We used optical micrometry by measuring the degree of swelling of granules of crosslinked polyvinyl alcohol in a test solution. To determine the concentration, the test solution was successively diluted, and a set of polymer swelling values was obtained. The data were used to build a total calibration curve for this mixture. Concentrations of the components of the solution were found by the least squares method, the software implementation of which is based on the coordinate descent.
