Question

Pleasee help me :(

If a solution of aspirin has a [H3O+] = 1.7 x10 -3 M, what is the pH of the solution?

Answer 1

2.77

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion concentration of a substance.

In order to find the pH we use the formula;

`\bold{pH = -log([{H_3O}^(+)])}`

From the question

`[{H_3O}^(+)]` =
`{1.7 * 10}^(-3) \: M`

We have

`pH = -log({1.7 * 10}^(-3)) \\ = 2.769555`

We have the final answer as

pH = 2.77
