Crude sodium chloride obtained by crystallization of brine solution does not contain

  1. \( \mathrm{CaSO_4} \)
  2. \( \mathrm{MgSO_4} \)
  3. \( \mathrm{Na_2SO_4} \)
  4. \( \mathrm{MgCl_2} \)

Correct answer · Option 2

\( \mathrm{MgSO_4} \)

Explanation

Crude sodium chloride contains \( \mathrm{Na_2SO_4} \), \( \mathrm{CaSO_4} \), \( \mathrm{CaCl_2} \), and \( \mathrm{MgCl_2} \) as impurities, but not \( \mathrm{MgSO_4} \).
