A) 31.5 g
B) 126 g
C) 63 g
D) 6.3 g
Correct Answer: C
Solution :
\[20\,\text{ml}\,N\text{-}KMn{{O}_{4}}\cong 20\,\text{ml}\,\,N\text{-}oxalic\,acid\] \[\therefore \] Normality of oxalic acid solution = 1 N We know, \[w=\frac{NEV}{1000}=\frac{1\times 63\times 1000}{1000}\]You need to login to perform this action.
