By diluting a weak electrolyte, specific conductivity `(K_(c))` and equivalent conductivity `(lamda_(c))` change as

A

Both increase

B

K increases , A_(eq) decreases

C

K decrease , A_(aq) increase

D

Both decrease

Text Solution

Verified by Experts

The correct Answer is:
C
On dilution, dissociation of weak electrolyte increases and also it increases the movability of ions in the solution. Since conductivity measurement requires unit volume solution no. of ions decreases on dilution, but conductivity measurement uses whole solution containing one equivalent electrolyte, causes increase the in no. of ions.
