Question

Which base is the strongest for the given [H+]? 10-9 10-11 10-10 10-12

Answer 1

The answer is 10-12. The relationship of pH and [H+] is pH = -lg[H+]. And the higher pH, the stronger base is. So the strongest base has the lowest concentration of H+.

Answer 2

Answer:The strongest base with
`H^+]` concentration is
`[H^+]=10^(-12) M`.

Step-by-step explanation:

`pH=-\log[H^+]`

Higher the pH value less will be the concentration of
`[H^+]` ion concentration and stronger will be the base.

1.
`[H^+]=10^(-9) M`

`pH=-\log[10^(-9)]=9`

2.
`[H^+]=10^(-11) M`

`pH=-\log[10^(-11)]=11`

3.
`[H^+]=10^(-10) M`

`pH=-\log[10^(-10)]=10`

4.
`[H^+]=10^(-12) M`

`pH=-\log[10^(-12)]=12`

The strongest base with
`H^+`concentration is
`[H^+]=10^(-12) M`.
