Answer: The given statement is true.
Explanation:
When we measure the pH of a substance then we get to know whether the given substance is acidic or basic in nature.
If pH of the substance is less than 7 then substance is acidic in nature but if pH is greater than 7 then substance is basic in nature. Whereas pH equal to 7 means substance is neutral.
Hardness of water is the measurement of calcium and magnesium dissolved in water. So, when pH of water becomes less than 7 then it becomes hard in nature.
Therefore, we can conclude that the statement hardness of water is a measurement of how acidic it is, true.
