Question

20 ml of a N-solution of KMnO4, just reacts with 20 ml of a solution of oxalic acid. The weight of oxalic acid crystals 1 litre of the solution is: (A) 31.5 g (B) 126 g (C) 63 g (D) 6.3 g

20 textml N text-KMnO4≅ 20 textml N text-oxalic acid ∴ Normality of oxalic acid solution = 1 N We know, w=(NEV/1000)=(1× 63× 1000/1000)

Q. 20 ml of a N-solution of $K M n O_{4},$ just reacts with 20 ml of a solution of oxalic acid. The weight of oxalic acid crystals 1 litre of the solution is:

31.5 g

126 g

63 g

6.3 g

$20 ml N - K M n O_{4} ≅ 20 ml N - o x a l i c a c i d$ $∴$ Normality of oxalic acid solution = 1 N We know, $w = \frac{NE V}{1000} = \frac{1 \times 63 \times 1000}{1000}$

Q. 20 ml of a N-solution of KMnO4​, just reacts with 20 ml of a solution of oxalic acid. The weight of oxalic acid crystals 1 litre of the solution is:
