The full range universal indicator turns to red colour when it is added to the beaker. And, this acid is a strong acid.
Explanation:
- Universal indicator is a pH paper or a solution that is made up of multiple compounds. When different solutions are added, its colour changes. It is used to find out whether the provided solution is a base or acid.
- When HCl is treated with the universal indicator, it gives a red color. HCl has a pH of 1. When the pH value drips, the acidity raises.
