Question

$1.575\, g\, H _{2} C _{2} O _{4} \cdot 2 H _{2} O$ in $250 \,mL$ solution makes it $0.1 \,N$. $H _{2} C _{2} O _{4} \cdot 2 H _{2} O$ is a dihydrate organic acid.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (B)

If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion

Answer 2

$W =\frac{E N V}{1000}$ $N =\frac{1.575 \times 1000}{63 \times 250}$ $\left[\because E\right.$ of $\left.H _{2} C _{2} O _{4} \cdot 2 H _{2} O =\frac{126}{2}=63\right]$ $=0.1 \,N$ $H _{2} C _{2} O _{4} \cdot 2 H _{2} O$ is an organic acid which contains 2 molecules of water of crystallisation.
