Which metal causes LiCl crystals to appear pink and KCl crystals to appear violet (or lilac) due to metal excess defects?

Options

  1. ASodium
  2. BLithium
  3. CPotassium
  4. DZinc

Correct answer

C. Potassium

Step-by-step solution

Excess of potassium makes KCl crystals violet (or lilac), resulting from metal excess defects.
