8. Solving a chemistry problem

2.1. According to the given quality of the source water (Larin B.M. “Physical and chemical calculations and analysis of ionic equilibria in solutions and technological waters of thermal power plants” Uch. allowance, Ivanovo, 1992. Appendix 3, pp. 106-107) calculate the following physical and chemical indicators :
• ionic strength of the solution (μ);
• activity coefficients of monovalent (γI) and divalent (γII) ions;
• electrical conductivity χ Ohm-1*cm-1;
• pH of the solution at a concentration of carbon dioxide Н2СО3 equal to 1 mol/dm3;
• stability of source water.
