Asolution has a hydrogen ion concentration of 6.8 10–3 m. (2 points) i. what is the ph of the solution? show your work.

2.17

Explanation:

To calculate pH using the hygrogen ion concentration we must use the following formula:

- log (H+) = pH

All we have to do now is plug in our hygrogen ion concentration and put it in our calculator.

- log (6.8 × 10⁻³) = 2.17

Don't forget proper figures for pH!
