Question

What will you observe when dilute ethanoic acid and dilute hydrochloric acid are put on universal indicator paper, one by one? What does it show?

Solution

When dilute ethanoic acid is put on a universal indicator paper, it turns the paper orange, marking the pH level to be 4. This shows that dilute ethanoic acid is a weak acid. On the other hand, when dilute hydrochloric acid is dropped on the universal indicator paper, it turns the paper red, marking its pH level to be about -1. This shows that hydrochloric acid is a strong acid.

  Is there an error in this question or solution?
