The ph of four different solutions are recorded below which solution is more acidic a. ph=3 b. ph=7 c. ph=10 d. ph=14

Solution a is the most acidic.

In a pH scale of 1 to 14, the smaller the pH is, the more acidic is. In opposite, the higher the pH is, the more alkaline it is. We call substances with pH below 7 as acid, and above 7 as alkali, while 7 as neutral.

Therefore, comparing the 4 solutions, solution a has the lowest pH, 3, so it is the most acidic.

A. mitochondrion b. nucleus
