Addition of CdCl₂ to AgCl yields solid solution where the divalent cations Cd²⁺ occupy the Ag⁺ sites. Which one of the following statements is true?

The no. of cationic vacancies is equal to that of divalent ions added.

The no. of cationic vacancies is one half of the no. of that of divalent ions added.

The no. of anionic vacancies is equal in no. to that of divalent ions added

No cationic or anionic vacancies are produced.
