Question

A solution ‘X’ gives orange colour when a drop of universal indicator is added to it. On the other hand, another solution ‘Y’ gives bluish-green colour when a drop of universal indicator is added to it. What are the types of solution ‘X’ and ‘Y’ and what type of pH would they have?

Answer 1

a)X is weakly acidic as it gives orange colour.
Y is Weakly basic as it gives bluish green.

b)pH of X=3-6.
pH of Y=7-9.

Answer 2

Answer:

Solution which gives Orange colour with universal indicator is weakly acidic and pH is between 3-6.

The solution which gives bluish green colour is a weak base and the pH of the solution is 7-8.

Explanation:

Universal indicator indicates the nature of solution and pH range.

Strong acids give red colour and weak acids give orange colour.

Strong bases give blue colour and weak bases give bluish green colour.
