3.1.12.2 Definition and determination of pH (A-level only)
| Content | Opportunities for skills development |
|---|---|
The concentration of hydrogen ions in aqueous solution covers a very wide range. Therefore, a logarithmic scale, the pH scale, is used as a measure of hydrogen ion concentration. |
Students should be able to:
convert concentration of hydrogen ions into pH and vice versa
calculate the pH of a solution of a strong acid from its concentration.
MS 0.4 Students carry out pH calculations. MS 2.5 Students could be given concentration values and asked to calculate pH or vice versa. |
