Comprehension # 5
`342 g` of `20%` by mass of `Ba(OH)_(2)` solution `(sp.gr.0.57)` is reacted with `200mL` of `2M HNO_(3)` according to given balanced reaction :
`Ba(OH)_(2)+2HNO_(3) rarr Ba(NO_(3))_(2) + 2H_(2)O`
Find the molarity of the ion in resulting solution by which nature of the above solution is identified, is

A

`0.5 M`

B

`0.8 M`

C

`0.4 M`

D

`1 M`

Text Solution

Verified by Experts

The correct Answer is:
A
Vol. of `Ba(OH)_(2)`
`=(342)/(0.57) = 600 mL`
mole of `OH^(-) = 0.2 xx 2 = 0.4`
molarity of `OH^(-) = (0.4)/(0.8) = 0.5`
