25 mL of a solution of barium hydroxide ...

25 mL of a solution of barium hydroxide on titration with 0.1 molar solution of hydrochloric acid gave a titre value of 35 mL. The molarity of barium hydroxide solution was

A

`0.07`

B

`0.14`

C

`0.28`

D

`0.35`

Text Solution

Verified by Experts

The correct Answer is:
A
For HCl M = N = 0.1
`N_(1)V_(1)=N_(2)V_(2) , 25xxN_(1)=0.1xx35`
`N_(1)=(0.1xx35)/(25), therefore M=(0.1xx35)/(25xx2)=0.07`.
