1. We filled a conductivity cell with KCl solution of 0.0400 mol dm−3 and its conductance at 25 °C was 2.102 mS. Calculate the cell constant. The conductivity of KCl solution at

25 °C is 2.770×10−3 S cm−1.

2. The molar conductivity for formic acid of 0.1 M concentration is 17.00 S cm2/mol. For an infinite dilution, this datum is 404.1 S cm2/mol. Calculate the degree of dissociation and the dissociation constant.

3. The conductivity for an acetic acid solution of 0.0316 M concentration is 9.260×10−3

S cm−1. Calculate the molar conductivity of the solution.
