Question

While performing an experiment at home, Emma adds lemon juice to a soap solution. How will this affect the pH of the soap solution?

A. The pH will remain constant.
B. The pH will increase.
C. The pH will decrease.

Answer 1

Its C. The pH will DECREASE

Answer 2

First, you need to know that the pH of lemon juice is very low, around 2. If you add lemon juice to a soap solution, you know that the pH would decrease since the pH of the soap solution would naturally be higher than the pH of the lemon juice, so adding lemon juice would lower the pH of the soap solution.
