Question

Molten silver chloride containing a little cadmium chloride is crystallized. Which of the following statements would explain the above crystal correctly?

• A. Each cadmium ion replaces two silver ions
• B. Number of cationic vacancies produced is equal to cadmium ions
• C. The crystals exhibits impurity defect
• D. All of the above

Answer 1

The correct option is A Each cadmium ion replaces two silver ions

Charge on Silver $\left(A{g}^{+}\right)$ ion is $+1$

Charge on Cadmium $\left(C{d}^{2+}\right)$ ion is $+2$

So, to maintain electrical neutrality if one cadmium ion is introduced in the $AgCl$ lattice, it will replace two silver ions.
