The `pH` of NaOH solution is `13`. What is the amount in grams of `NaOH` present in one litre of a solution?

A

40

B

4

C

`0.4`

D

20

Text Solution

Verified by Experts

The correct Answer is:
B
`OP^(OH)=14-P^(H)=14-12=2`
`[OH^(-)]=N=10^(-POH)=10^(-2)N`
`N=(W)/(EW)xx(1)/(V(lit))`
`10^(-2)=(w)/(eq.w)xx(1)/(v), w=10^(-2)xx40xx1=0.4`
