0.115 gm of sodium metal was dissolved in 500 ml of the solution in distilled water. The normality of the solution would be

A

`0.010N`

B

`0.0115N`

C

`0.023N`

D

`0.046N`

Text Solution

Verified by Experts

The correct Answer is:
A
`Na+H_(2)OrarrNaOH+(1)/(2)H_(2)`
0.115 gm Na implies 0.005 moles NaOH
`M=(0.005)/(0.5)=0.01N`
