Select correct statement when is added to KCl crystal :
Options:(select one or more)
Answer:
B, D
Solution:
When CaCl₂ is added to a KCl crystal, it introduces an impurity defect. For every Ca²⁺ ion (charge +2) replacing two K⁺ ions (charge +1 each), one K⁺ site is occupied by Ca²⁺, and the other K⁺ site becomes a cation vacancy to maintain electrical neutrality. This decreases the crystal's density.
The final answer is B and D.
