If x gm is the mass of NaHC 2 O 4 required to neutralise 100 ml of 0.2 (M) NaOH and y gm that required to reduce 100 ml of 0.02 (M) KMnO 4 in acidic medium, then
Text Solution
Verified by ExpertsThe correct answer is:
C
Let mol wt. of NaHC 2 O 4 = M
∴ 
= 100 × 0.2 × 10 –3 = 20 × 10 –3 ------(I)
× 
= 100 × 0.02 ×10 –3 = 2 × 10 –3 ------II)
Dividing equation (I) by equation (II)
× 
= 10
or x = 4y
