Some Basic Concepts Of Chemistry Question 245

Question: $K M n O_{4}$ reacts with ferrous ammonium sulphate according to the equation $M n O_{4}^{-} + 5 F e^{2 +} + 8 H^{+} \to M n^{2 +} + 5 F e^{3 +} + 4 H_{2} O$ , here 10 ml of 0.1 M $K M n O_{4}$ is equivalent to [CPMT 1999]

Options:

A) 20 ml of 0.1 M $F e S O_{4}$

B) 30 ml of 0.1 M $F e S O_{4}$

C) 40 ml of 0.1 M $F e S O_{4}$

D) 50 ml of 0.1 M $F e S O_{4}$

Show Answer

Answer:

Correct Answer: D

Solution:

$K M n O_{4} =$ Mohr salt $\frac{M_{1} V_{1}}{n_{1}} = \frac{M_{2} V_{2}}{n_{2}}$ ; $\frac{0.1 \times 10}{1} = \frac{M_{2} V_{2}}{5}$ ; $M_{2} V_{2} = 5$ .
