Question

What is the pH of 5.34 x 10^-6 M NaOH?

Answer 1

The pH is 8.73

Step-by-step explanation:

In water,

`p^(H) + p^(0H) = 14`

`p^(H) = 14 - p^(0H)`

`p^(0H) = -log_(10)(H0^(-))`

Thus,

`p^(p0H) = -log_(10)(5.34×10^(-6))`

`p^(0H) = -(-5.27)`

`p^(0H) = 5.27)`

Hence, we substitute;

`p^(H) = 14 - p^(0H)`

pH = 14 - 5.27

pH = 8.73
