The conductivity of 0.001M Na2SO4 solution is 2.6×10−4 Scm−1 and – InterviewSolution

1.	The conductivity of 0.001M Na2SO4 solution is 2.6×10−4 Scm−1 and increases to 7.0×10−4 Scm−1, when the solution is saturated with CaSO4. The molar conductivities of Na+ and Ca2+ are 50 and 120 Scm2mol−1, respectively. Neglect conductivity of used water. What is the solubility product of CaSO4?
Answer» The conductivity of $0.001 M N a_{2} S O_{4} solution is 2.6 \times 10^{- 4} S c m^{- 1}$ and increases to $7.0 \times 10^{- 4} S c m^{- 1}$ , when the solution is saturated with $C a S O_{4} .$ The molar conductivities of $N a^{+} and C a^{2 +} are 50 and 120 S c m^{2} m o l^{- 1}$ , respectively. Neglect conductivity of used water. What is the solubility product of $C a S O_{4} ?$
