Question

In the given graph, which compound would be the most approximately to be easily purified by crystallisation from water?

• A. $NaCl$
• B. $CaC{O}_3$
• C. $Ca{F}_2$
• D. $ZnS$

Answer 1

The correct option is A $NaCl$

$\begin{array}{c}\text{According to given diagram, NaCl doesn't have high solubility}\\ \text{even at elevated temperature.}\\ \text{Thus, by crystallisation, NaCl can be easily purified .}\\ \text{so, option (A) is correct.}\end{array}$
Option A is correct.
