Question

Two solutions X and Y have pH = 2 and pH = 4, respectively. Which solution will give alkaline reaction and which one acidic?

a) Solution X is acidic, Solution Y is alkaline
b) Solution X is alkaline, Solution Y is acidic
c) Both Solution X and Solution Y are acidic
d) Both Solution X and Solution Y are alkaline

Answer 1

Both Solution X and Solution Y are acidic.

Step-by-step explanation:

The pH scale is used to measure the acidity or alkalinity of a solution. A pH value below 7 indicates an acidic solution, a pH value of 7 indicates a neutral solution, and a pH value above 7 indicates an alkaline solution.

In this case, Solution X has a pH of 2, which is below 7, so it is acidic. Solution Y has a pH of 4, which is also below 7, so it is also acidic.

Therefore, the correct answer is: Both Solution X and Solution Y are acidic.
