Question

Solution A gives pink colour when a drop of phenolphthalein indicator is added to it. Solution B gives red colour when a drop of methly orange is added to it. What type of solution are A and B and which one of the solution A and B will have a higher pH value?

Answer 1

SOLUTION A IS BASE.
SOLUTION B IS ACID.
AS BASES SOLUTIONS HAVE A pH MORE THAN 7.
SOLUTION A WILL HAVE A HIGHER pH VALUE.

PLS MARK AS BRAINLEIST.

Answer 2

Explanation:

Solution A is basic solution the pH range in between 7 to 14

Solution B is acidic solution the pH range in between 0 to 7.

Hence, solution A has higher pH value.

The chemical substances which are useful to identify the acidic or basic behavior of the solutions by changing of their color are known as acid – base indicator.

The example is in the image given below.

Solution A gives pink color when a drop of phenolphthalein indicator is added to it, hence, it is a basic solution and pH range in between 9-10.

Solution B gives red color when a drop of methyl orange is added to it, hence, it is an acidic solution and pH range in between 4-6.

Therefore, solution A has higher pH value.
