Question

The crystalline salt Na 2 SO 4 ⋅ xH 2 O on heating loses 55.9 % of its mass ad becomes anhydrous. The formula of crystalline salt is (A) Na 2 SO 4 ⋅ 5 H 2 O (B) Na 2 SO 4 ⋅ 7 H 2 O (C) Na 2 SO 4.2 H 2 O (D) Na 2 SO 4 ⋅ 10 H 2 O

Tardigrade Admin · Accepted Answer

Correct answer is (d) Na 2 SO 4 ⋅ 10 H 2 O

Q. The crystalline salt $N a_{2} S O_{4} \cdot x H_{2} O$ on heating loses $55.9%$ of its mass ad becomes anhydrous. The formula of crystalline salt is

$N a_{2} S O_{4} \cdot 5 H_{2} O$

$N a_{2} S O_{4} \cdot 7 H_{2} O$

$N a_{2} SO 4.2 H_{2} O$

$N a_{2} S O_{4} \cdot 10 H_{2} O$

Correct answer is (d) $N a_{2} S O_{4} \cdot 10 H_{2} O$
