25 mL of a solution of barium hydroxide ...

25 mL of a solution of barium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a titre value of 35 mL. The molarity of barium hydroxide solutions 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_1V_1 = N_2V_2, 25xx N_1 = 0.1 xx 35`
`N_1=(0.1xx35)/25, :. M = (0.1xx35)/(25xx2)=0.07`
