Product description
- The analyzed mixture of HCl and CH3COOH was placed in a volumetric flask with a capacity of 50 ml and made up to the mark with water. When titrating 10.0 ml of NaOH solution with a concentration of 0.1 mol / L (K = 1.104), the following results were obtained for numbers
tasks - table 24 (electrical conductivity χ • 103 cm). Plot the titration curve and determine the mass (g) of HCl and CH3COOH in the original solution.
