Answer:
A pH scale is a scale of measurement that describes the level of acidity or alkalinity of a solution.
The pH range of an acid is below 7.0; base is above 7.0, and pure water is 7.0
Explanation:
A pH scale is a scale of measurement that describes the level of acidity or alkalinity of a substance. It reads numerical values from 0 to 14.0 where values of 0 to 6.99 represent acid; 7 represent neutral; and values above 7.0 to 14.0 represent alkaline (base).
Phase change graphs are a graphical representation of physical states substance under different conditions of temperature and pressure. Two states of the substance coexist in equilibrium on the lines.

Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.
