S1 : Conductivity always increases with decrease in the concentration of electrolyte. |
S2 : Molar conductivity always increases with decrease in the concentration of electrolyte. |
A) Both S1 and S2 are correct
B) S1 is wrong and S2 is correct
C) S1 is correct and S2 is wrong
D) Both S1 and S2 are wrong
Correct Answer: B
Solution :
On dilution, no. of ions per ml decreases so conductivity decreases hence S1 is wrong. \[{{\wedge }_{M}}=\frac{1000\times \kappa }{C}\] On dilution C and \[\kappa \]both decreases but effect of C is more dominating so \[{{\wedge }_{M}}\]increases hence S2 is right.You need to login to perform this action.
