Two Solution X and Y are tested the universal indicator. Solution X turns orange whereas solution Y turns red. Which of the solutions is a stronger acid?

Strong Acids are those acids that dissociate completely in water and produces a large number of hydrogen ions.

Example of strong acids include HCl and H₂SO₄

Solution Y is a stronger acid as the red colour of the solution Y indicates a pH value of 1 while the orange colour Indicates a pH value higher than 1.
