Strong acid

[Gisela F Ramirez 2H]

Why is HCl a strong acid?

[Ethan Yi 1K]

it is easily ionized

[Albert_Luu3K]

It is a strong acid because it fully ionizes and dissociates in water. That means there are more hydronium ions in solution making it more acidic.

[Nicholas Le 4H]

HCl is a strong acid as the most of the halogens in group 7 except flourine form strong acids due to the fact that they pull the electron density from hydrogen, and as it goes down the group the bond gets weaker and thus increases the strength of the acidity.

[Nghi Nguyen 2L]

it fully ionizes/dissociates in a solution

[Manas_Varma_4B]

It is a strong acid because it fully ionizes in water, it fully disassociates.

[Eva Zhao 3B]

Strong acids almost completely ionize in solution. HCl, which dissociates completely, is a strong acid. Therefore, 0.1 M HCl(aq) implies 0.1 M H₃O⁺(aq) and 0.1 M Cl^-(aq).
