Question

A solution has a [OH-] = 8.6 x 10-5.

Answer the following questions.

pOH =
pH =
[H+] =

Answer 1

pOH = 4
pH = 10
[H+] = 1 X 10^-10

Answer 2

Answer: pOH= 4.06

pH= 9.94

`[H^+]=1.14* 10^(-10)M`

Explanation: pOH is the negative logarithm of
`OH^-` concentration.

pH is the negative logarithm of
`H^+` concentration.

`pOH=-log[OH^-]`

`pOH=-log[8.6* 10^(-5)]=4.06`

2)
`pH+pOH=14`

`pH=14-4.06`

`pH=9.94`

3)
`pH=-log[H^+]`

`9.94=-log[H^+]`

`[H^+]=1.14* 10^(-10)M`
