Question

The image shows the pH values of four solutions on a pH scale.Which solutions are alkaline in nature?​

Answer 1

C and D solutions are alkaline in nature. (option c)

• By pH scale we can determine the nature of a solution in the following way -

1. If pH of a solution is greater than 7 then it is alkaline in nature.
2. If pH of a solution is less than 7 then it is acidic in nature.
3. If pH of a solution is equal to 7 then it is neutral in nature.

• Now, among the given solutions (A,B,C and D) only C and D solutions have a value of pH which is greater than 7.
• That's why, solution C and solution D are alkaline in nature.
