Question

HCl was passed through a solution of CaCl2,MgCl2 and NaCl. Which of the following compound(s) crystallise(a)? (A) Both MgCl2 and CaCl2 (B) Only NaCl (C) Only MgCl2 (D) NaCl, MgCl2 and CaCl2

On passing HCl through aqueous solution of CaCl2, MgCl2 and NaCl, crystals of pure NaCl seperate out. Calcium and magnesium chloride being more soluble than NaCl, remain in solution.

Q. HCl was passed through a solution of $C a C l_{2}$ , $M g C l_{2}$ and $N a Cl$ . Which of the following compound(s) crystallise(a)?

Both $M g C l_{2}$ and $C a C l_{2}$

Only $N a Cl$

Only $M g C l_{2}$

$N a Cl$ , $M g C l_{2}$ and $C a C l_{2}$

On passing $H Cl$ through aqueous solution of $C a C l_{2}, M g C l_{2}$ and $N a Cl$ , crystals of pure $N a Cl$ seperate out. Calcium and magnesium chloride being more soluble than $N a Cl$ , remain in solution.
