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 if universal indicator is added to it. What type of solution is x and y?

Answer 1

solution x-It is a moderately acidic solution(ph value 3)

solution y-it is slightly basic (ph value 8 or 7-9)

Answer 2

Universal indicator is used in determination of strength of acid or base.It helps us to know about the pH of the given solution. But the litmus paper helps us know whether a solution is acid or base.

             The solution X gives orange colour that indicates the solution is weakly acidic and pH value is 4 & Solution  Y become bluish green on adding universal indicator which indicates solution is weakly basic and the pH ranges from 8-9
