100 mL ofO.1 N NaOH solution is required for neutralisation of 0.49 g of a dibasic acid. What is the molecular weight of the acid?

A

49

B

98

C

490

D

196

Text Solution

Verified by Experts

The correct Answer is:
B
Milliequivalents of acid = Milliequivalents of base ` (0.49 )/(E ) xx 100 =0.1 xx 100` (Say equivalent wt. of acid = E)
` therefore E= 49`
Molecular weight =Equivalent weight `xx` Basicity `= 49 xx 2 = 98`
