Question

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH of the clean compound the pH is approximately

Answer 1

The
`pH` of the clean compound is approximately 10.495.

Explanation:

If the cleaning ion concentration of the cleaning compound is
`[H^(+)] = 3.2* 10^(-11)`, then the
`pH`, no unit, of the compound is:

`pH = -\log_(10) [H^(+)]` (1)

`pH = -\log_(10) (3.2* 10^(-11))`

`pH = -\log_(10) 3.2 - \log_(10) (10^(-11))`

`pH = -\log_(10) (32)/(10) +11`

`pH = -\log_(10) 32 + \log_(10) 10 + 11`

`pH = -\log_(10) 32 +12`

`pH \approx 10.495`

The
`pH` of the clean compound is approximately 10.495.
