Because it completely dissasociates in water.

It completely dissociates in water and increases the [H3O^+] concentration thus decreasing pH.

A strong acid is based on the bond between the H+ part of the molecule, and the negative ion. So HCl is totally fine separating into H+ and Cl- which makes it a strong acid.

When we measure pH, we are talking about the amount of H+/H3O+ (which is H+ + H2O -> H3O+). The greater a concentration of H3O+, the more acidic.

Molecules like H2CO3, are much less likely to dissociate in water (of course there will be a little, but that is what makes it weak).

Acid solutions contain hydrogen ions. The higher the concentration of hydrogen ions, the lower the pH. A strong acid also completely dissociates in water.

A strong acid can completely disassociate in water. As they have hydrogen ions, the higher the hydrogen concentration, the lower the pH is. In a compound it is dependent on the H bond and the negative ion.

Strong acids almost always dissociate completely to yield hydronium ions.

When a strong acid dissociates, this yields a high concentration of H+ ions. Using the equation pH=-log[H+], you will find that the pH is very low which correlates to a strong acid.

They dissociate completely in water to form hydronium ions. Examples would be HCl, HBr, HNO3 etc.
