Why Is Hydrochloric Acid a Strong Acid?

HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule. In summary: the stronger the acid the more free H+ ions are released into solution.

Why is HCl a strong acid class 10?

HCl is a strong acid because it has more number of hydrogen ions whereas acetic acid contains less number of hydrogen ions so its a weak acid , it can be varied by changing number of hydrogen ions in them .

What makes a strong acid?

Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than a hydronium ion, so its pKa must be lower than that of a hydronium ion. Therefore, strong acids have a pKa of <-174. ... Strong acids must be handled carefully because they can cause severe chemical burns.
