25 ml of the given HCl solution requires 30 mL of 0.1M sodium carbonate solution. What is the volume of this HCl solution required to titrate 30 mL of 0.2M aqueous NaOH solution ?

A

12.5mL

B

75mL

C

50mL

D

25mL

Text Solution

Verified by Experts

The correct Answer is:
D
Eq. of HCl = Eq. of `Na_2CO_3`
`25xx N = 2xx0.1xx30`
HCI = 0.24 N
Eq. of HCI = Eq. of NaOH
`0.24xxV = 30xx0.2`
V = 25 mL
