### Correct Word Selection

1. **Break Down the Problem**
We need to identify the correct word that accurately completes the sentence about the pH scale.

2. **Relevant Concepts**
The pH scale is a measurement system used in chemistry to determine how acidic or basic a substance is. The key aspect to look for is what pH indicates regarding acids and bases.

3. **Analysis and Detail**
- **Taste**: While some acids and bases can be sour or bitter, taste is not measured by the pH scale.
- **Strength**: The pH scale effectively measures the strength of acids and bases, indicating how concentrated they are in terms of hydrogen ion concentration.
- **Colour**: Colour is not a direct measurement of acids and bases on the pH scale.
- **Temperature**: Though temperature affects chemical reactions, it does not relate to the pH measurement itself.

4. **Verify and Summarize**
After considering the definitions, "strength" is the most suitable term because the pH scale quantifies how acidic or basic a solution is, which is directly related to the strength of acids and bases.

### Final Answer
The pH scale allows us to measure the **strength** of acids and bases.
