Final answer:
pH stands for the negative logarithm of the hydrogen ion concentration. The statement is true.
Step-by-step explanation:
The statement is true. pH stands for the negative logarithm of the hydrogen ion concentration. It is a scale used to measure the acidity or basicity of a solution. The lower the pH value, the more acidic the solution is, while a higher pH value indicates a more basic solution. For example, a solution with a pH of 1 is highly acidic, while a solution with a pH of 14 is highly basic.
