JEE MAIN - Chemistry (2020 - 3rd September Morning Slot - No. 11)

Let C_NaCl and C_BaSO₄ be the conductances (in S) measured for saturated aqueous solutions of NaCl and BaSO₄, respectively, at a temperature T. Which of the following is false?

Ionic mobilities of ions from both salts increase with T.

C_NaCl(T₂) > C_NaCl(T₁) for T₂ > T₁

C_BaSO₄(T₂) > C_BaSO₄(T₁) for T₂ > T₁

C_NaCl >> C_BaSO₄ at a given T

Explanation

BaSO₄ is sparingly soluble salt but NaCl is completely soluble salt so it will produce more number of ions. That is why
Conductance (NaCl) > Conductance (BaSO₄)
