Final answer:

The likely pH of the clear, sour-tasting liquid is below 7, indicating that it is acidic. The pH scale defines substances with pH below 7 as acidic, and the sour taste is a common indicator of an acidic substance.

Step-by-step explanation:

The clear, sour-tasting liquid is likely to have a pH below 7, as sour taste is characteristic of acidic substances. The pH scale is a measure of how acidic or basic (alkaline) a solution is. Pure water, with a pH of 7, is considered neutral. Anything with a pH less than 7 is acidic, while a pH greater than 7 is basic (alkaline).

To illustrate the concept, here are some examples of substances with their corresponding pH values:

  • Human blood has a pH of 7.4, which is slightly alkaline.
  • Household ammonia has a pH of 11.0, which is basic.
  • Cherries have a pH of 3.6, which is acidic.

Therefore, based on the sour taste, which indicates acidity, the pH of the liquid in question is likely c. Below 7.
