What does the pH of 3 tell you about the extent of hydrolysis of hydrochloric acid?

Question

We added one drop of methyl violet indicator to a test-tube containing 20 drops of 0.1M HCl, and the pH of the solution was 3. What does the pH tell you about the extent of hydrolysis of hydrochloric acid?

Answer 1

0.1 M HCl should have a pH of 1, so if you get a pH of 3, it says that the HCl is not completely dissociated. Don't know why this would be the case, however.
