Answer:
Solution A- pH of 5 (Acidic)
 Solution B- pH of 11 (Basic)
 Solution C- pH of 7 (Neutral)
Step-by-step 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.
