Answer: The sentence given is false.

Step-by-step explanation:

The question requires us to determine if the sentence given by the question ("pH can only be between 1 and 14") is true or false.

The pH value is matematically defined as:


pH=-log\lbrack H^+\rbrack

where [H+] is the concentration of H+ ions in solution.

If the concentration of H+ is too high, such as in an acid battery, the pH of a solution can reach 0. However, its value cannot be negative. Therefore, we can say that the pH scale ranges from 0 (very acidic medium) to 14 (very alkaline medium).

Considering the sentence given, we can say that it is false.
