Equal volums of solutions pH values 1,3,...

Equal volums of solutions `pH` values `1,3,5,6` are mixed with each other . The pH of resultant solution is nearly

A

`1.3`

B

`2.7`

C

`1.6`

D

`3.6`

Text Solution

Verified by Experts

The correct Answer is:
C
`[H^(+)]=(10^(-1)v+10^(-3)v+10^(-5)v+10^(-6)v)/(4v)=(10^(-1)v)/(4v)`
`=0.25xx10^(-1)=2.5xx10^(-2)`
`P^(H)=-log.2.5xx10^(-2)-log2.5`
`P^(H)=1.6`
