Question

A solution has a hydrogen ion concentration of 6.8 10–3 M. (2 points) i. What is the pH of the solution? Show your work.

Answer 1

Answer:

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!
