Assertion. When 1.0 mol of NaCl is doped with `10^(-3)` mol `SrCl_2`, the number of cationic sites remaining vacant is `10^(-3)`
Reason. Each `SrCl_2` unit produces two cation vacancies.

Text Solution

Verified by Experts

The correct Answer is:
a
Correct A. As each `SrCl_(2)` unit creates one cation vacancy, number of cation vacancies will be ` 10^(-3) " mol" = 10^(-3) xx ( 6.02 xx 10^(23)) = 6.02 xx 10^(20)`
Correct R. Each `SrCl_(2)` produces one cation vacancy .
