Question:
If molten NaCl contains SrCl$_2$ as impurity, crystallization can generate
If molten NaCl contains SrCl$_2$ as impurity, crystallization can generate
Show Hint
Divalent ion impurity in monovalent ionic lattice leads to cationic vacancies to balance charge.
Updated On: May 18, 2025
- Anionic vacancies
- Cationic vacancies
- Metal excess defects
- Metal deficiency defects
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Sr$^{2+}$ substitutes two Na$^+$ ions, but occupies only one lattice site, creating one Na$^+$ vacancy to maintain charge neutrality.
Thus, cationic vacancy is created.
Thus, cationic vacancy is created.
