If molten NaCl contains SrCl2 as impurity, crystallization can generate

  1. A Anionic vacancies
  2. B Cationic vacancies
  3. C Metal excess defects
  4. D Metal deficiency defects
Verified Solution

Answer & Solution

Correct Answer

(B) Cationic vacancies

Step-by-step Solution

Detailed explanation

If molten NaCl containing a little amount of SrCl2 is crystallised, some of the sites of Na+ ions are occupied by Sr2+. Each Sr2+ replaces two Na+ ions. It occupies the site of one ion and the other site remains vacant. The cationic vacancies thus produced are equal in number to…
