Why is HF a weak acid, but HCl is a strong acid?

Question:

Strong Acids

An acid is classified as strong if it dissociates in water completely to produce hydronium ions and counter anions. Strong acids have very large dissociation constants and are often not reported. Examples of strong acids are hydrochloric acid, sulfuric acid, and nitric acid.
