If molten contains as impurity, crystallization can generate
- A Anionic vacancies
- B Cationic vacancies
- C Metal excess defects
- D Metal deficiency defects
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…
