Final answer:

The claim that PHFs have pH values below 3.0 is false; that would mean they are very acidic. The pH value below 7 indicates an acidic solution, not specifically below 3.0. The pH scale typically ranges from 0 to 14, with 7 being neutral.

Step-by-step explanation:

The statement that PHFs have pH values below 3.0 is false. The pH scale is a measure of hydrogen ion concentration in a solution, and it typically ranges from 0 to 14. At standard temperature (25 °C), a solution with a pH value of 7.0 is considered neutral.

If the pH is below 7.0, the solution is acidic, while a pH above 7.0 means the solution is basic (also known as alkaline). The pH of a solution is defined as the negative logarithm of the hydrogen ion concentration, making it a positive value between 0 and 14.

It is important to note that the pH scale is dependent on temperature, where neutral pH is at 7.00 at 25 °C, but this value can shift slightly at other temperatures. In biological systems, pH control is essential for proper functioning, and pH ranges are critical for various environmental and cellular processes.
