Question

Write the correct equation for the conductivity of 1 M potassium sulfate

Answer 1

Molar conductivity can be calculated from the specific conductivity $\kappa$ and the concentration $C$ (in mol per l) of the substance in the electrolyte solution:

$$\Lambda = \frac {\kappa}{C}$$

As $C = 1 \, \text{mol/l} \, \Lambda$ of $\mathrm{K}_2\mathrm{SO}_4$ equals $\kappa$ of this solution.

$$\Lambda = \kappa$$
