Conductivity ( kappa) of 0.01 M NaCl solution is 0.00145 S cm -1. What happens to the conductivity if extra 100 mL of H 2 O be added to the above solution?

Question

Conductivity ( kappa) of 0.01 M NaCl solution is 0.00145 S cm -1. What happens to the conductivity if extra 100 mL of H 2 O be added to the above solution? (A) Decreases (B) Increases (C) Remains unchanged (D) First increases and then decreases

Molar conductance =( text Specific conductance / text Molarity ) On dilution, molarity decreases and molar conductance increases. Hence, specific conductance decreases.

Q. Conductivity $(κ)$ of $0.01 M N a Cl$ solution is $0.00145 S$ $c m^{- 1}$ . What happens to the conductivity if extra $100 m L$ of $H_{2} O$ be added to the above solution?

Decreases

Increases

Remains unchanged

First increases and then decreases

Molar conductance $= \frac{Specific conductance}{Molarity}$

On dilution, molarity decreases and molar conductance increases. Hence, specific conductance decreases.
