Question

63. An aqueous solution of 6.3 g of oxalic acid dihydrate
is made up of to 250 ml. The volume of 0.1 M
NaOH required to completely neutralise 10 ml of
this solution is
(a) 40 ml
(b) 20 ml
(c) 10 ml
(d) 4 ml​

Answer 1

Answer:

So, the volume of 0.1 N NaOH required to neutralise 0.4 N and 10 mL solution of oxalic acid dihydrate is 40 mL. So, the correct answer is “Option A”. Note: The molecular formula of oxalic acid is C2H2O4 and its molecular weight is 90 g/mole while that of oxalic acid dihydrate is C2H2O4.
