A very low pH means high acidic water and the water will contain high concentration hydrogen ions [[tex]H^+[/tex]].
pH scale helps us to measure the acidic or basic nature of a substance or water.
- The range of pH scale is between 0 to 14,
- a pH of 7 indicates the neutral solution or substance.
- if the pH of the substance is low, that is less than 7, the substance is acidic.
- also, if the pH of the substance is high, that is greater than 7, the substance is alkaline.
In general, pH measures the relative amount of free hydrogen ion [[tex]H^+[/tex]] and hydroxyl ions [[tex]OH^{-1}[/tex]] present in a water.
- If a water contains high concentration of hydrogen ions [[tex]H^+[/tex]], then the water is acidic,
- Also, if the water contains high concentration of hydroxyl ions [[tex]OH^{-1}[/tex]] , then the water is basic.
Thus, a very low pH means high acidic water and the water will contain high concentration hydrogen ions [[tex]H^+[/tex]].
