A certain buffer solution contains equal concentartion of `X^(Theta)` and `HX`. The `K_(b)` for `X^(Theta)` is `10^(-10)`. The `pH` of the buffer is

Text Solution

Verified by Experts

The correct Answer is:
4
`pOH = pK_(b) + "log"(["salt"])/(["base"])`
[salt]=[base]
`pOH=pK_(b)`
`pOH=10 implies pH=14-10=4`
