Solution
pH is the measure of the concentration of ions and expresses the acidic or basic nature of the solution.
pH scale imparts different color depending on its pH value:
pH
Color
<3
red
3-6
orange
7
green
8-11
blue
11-13
purple
14
violet
Solution B is more basic in nature since the paper strip which imparts purple indicates a level of 11 and dark violet indicates the level of 14. Since the higher the pH level, the more basic the strength of a solution is, therefore, solution B is more basic.
