Question

Calculate the pH if [H+] = 3.95 x 10^-5 M

Answer 1

pH = 4.40

Step-by-step explanation

Given:

[H⁺] = 3.95 x 10⁻⁵ M

What to find:

The pH of the solution.

Step-by-step solution:

Using the pH formula;

`pH=-log[H^+]`

So,

`\begin{gathered} pH=-log(3.95*10^(-5)) \\ \\ pH=-(-4.40) \\ \\ pH=4.40 \end{gathered}`
