Question

Find the [H+] in an acetic acid solution that has a pH of 5.12

Answer 1

Data:
pH = 5.2
[H+] = ?

Knowing that: (Equation to find the pH of a solution)

`pH = -log[H+]`

Solving:

`pH = -log[H+]`

`5.2 = - log [H+]`
Knowing that the exponential is the opposite operation of the logarithm, then we have:

`[H+] = 10^(-5.2)`

`\boxed{\boxed{[H+] = 6.30*10^(-6)}}\end{array}}\qquad\quad\checkmark`
