Question

Crude sodium chloride contains:

• A. $\text{Only}N{a}_{2}S{O}_4$
• B. $\text{Only}CaS{O}_4$
• C. $N{a}_{2}S{O}_4,CaS{O}_4\text{and}CaC{l}_2$
• D. $\text{Only}CaS{O}_4\text{and}CaC{l}_2$

Answer 1

The correct option is C $N{a}_{2}S{O}_4,CaS{O}_4\text{and}CaC{l}_2$

Crude sodium chloride contains $N{a}_{2}S{O}_4,CaS{O}_4,CaC{l}_2$ and $MgC{l}_2$ as impurities.
