pH values for Common Liquids
pH is a measure of the acidity or alkalinity of a solution, indicating the concentration of hydrogen ions (H+) present. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral.
- Solutions with a pH less than 7 are acidic, with lower values indicating stronger acidity.
- Solutions with a pH greater than 7 are alkaline (basic), with higher values indicating stronger alkalinity.
