Question

What color does bromophenol blue exhibit in an acidic solution?

a) Blue
b) Red
c) Yellow
d) Green

Answer 1

Bromophenol blue exhibits a yellow color in an acidic solution.

Step-by-step explanation:

Bromophenol blue is an acid-base indicator commonly used in laboratories to determine the pH of a solution. In an acidic solution, bromophenol blue exhibits a yellow color. This is because in acidic conditions, the concentration of hydronium ions (H3O+) is high, and the indicator molecule changes its structure, resulting in a yellow color. Therefore, the correct answer to your question is c) Yellow.
