What do the numbers on the pH scale say about the solution?

Answer 1

acidic (lower than 7) neutral (7) and basic (higher than 7)

Answer 2

The numbers on the pH scale indicate the acidity or alkalinity of a solution. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. The lower the pH value, the more acidic the solution, and the higher the pH value, the more alkaline the solution.

Answer 3

pH is a measure of the concentration of hydronium in an aqueous solution; it is the negative log of that concentration. It can range from nearly -1 to above 15.

Answer 4

They identify the degree of acidity or alkalinity of the solution (pH 7 being neutral).
