Answer:

The pH is 8.73

Explanation:

In water,

[tex]p^{H} + p^{0H} = 14[/tex]

[tex]p^{H} = 14 - p^{0H}[/tex]

[tex]p^{0H} = -log_{10}(H0^{-})[/tex]

Thus,

[tex]p^{p0H} = -log_{10}(5.34×10^{-6})[/tex]

[tex]p^{0H} = -(-5.27)[/tex]

[tex]p^{0H} = 5.27)[/tex]

Hence, we substitute;

[tex]p^{H} = 14 - p^{0H}[/tex]

pH = 14 - 5.27

pH = 8.73
