उत्तर
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.
