Question

The `pH` of a sample of vinegar is `3.76`, Calculate the concentration of hydrogen ion in it.

Answer 1

Correct Answer - `1.7 xx 10^(-4) M`
Given
`pH = 3.76`
It is known that,
`pH = -"log"[H^(+)]`
`rArr "log"[H^(+)] = - pH`
`{:(rArr[H^(+)],="antilog"(-pH)),(,="antilog"(-3.76)),(,=1.74xx10^(-4)M):}`
