Answer:Acidity or alkalinity of a solution is measured by concentration of hydrogen ions (H+) versus hydroxyl ions (OH-) and is expressed as pH level, an exponential scale that ranges from 0 (very acidic) to 14 (very basic).

Explanation:

The values used to express the acidity or alkalinity of a solution Using the pH scale are;

values below 7 is acidity and values above 7 express alkalinity

Meaning of acidity and alkalinity

Acidity is the ability for a solution to neutralize a base while Alkalinity is the ability for a solution to neutralize an acid. The values that represent alkanity on the pH scale are above 7 while values below the value of 7 represent acidity.

Inconclusion The values used to express the acidity or alkalinity of a solution Using the pH scale are; values below 7 is acidity and values above 7 express alkalinity
