Question

A sample of Na2CO3⋅ H2O weighing 3.1 g is added to 100 mL of 0.5 NH2SO4, the resulting solution will be (A) acidic (B) amphoteric (C) basic (D) neutral

Tardigrade Admin · Accepted Answer

Normality of Na2CO3⋅ H2O solution = (3.1/62) × (1000/100) = 0.5 N Solution will be neutral since both H2SO4 and Na2CO3 ⋅ H2O are of same normality.

Q. A sample of $N a_{2} C O_{3} \cdot H_{2} O$ weighing $3.1 g$ is added to $100 m L$ of $0.5 N H_{2} S O_{4}$ , the resulting solution will be

acidic

amphoteric

basic

neutral

Normality of $N a_{2} C O_{3} \cdot H_{2} O$ solution
$= \frac{3.1}{62} \times \frac{1000}{100} = 0.5 N$
Solution will be neutral since both $H_{2} S O_{4}$ and $N a_{2} C O_{3} \cdot H_{2} O$ are of same normality.
