Solution A - pH of 5 Solution B - pH of 11 Solution C - pH of 7 Acidic Basic Neutral

Solution A - pH of 5 (Acidic)

Solution B - pH of 11 (Basic)

Solution C - pH of 7 (Neutral)

Explanation:

The value of pH of a solution tells its degree of acidity or alkalinity. pH values range from 0 to 14 where:

- any pH value below 7 is said to be acidic

- any pH value at 7 is said to be neutral

- any pH value above 7 is said to be basic

Thus, Solution A is Acidic; Solution B is Basic; Solution C is Neutral.
