Read this paragraph and choose the correct option from the provided answers:

The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4).

 Choices:

- mass

- density

- color

- ph


A:
ph
