✓ Answer:
C
7
The pH scale ranges from 0 to 14 and is used to measure the acidity or basicity of a solution. A pH value of 7 is considered neutral, meaning the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-). Solutions with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline.
