Because HCl, HBr, and HI ionize completely when dissolved in water..
HCl + H2O → H3O+ + Cl-
HBr + H2O → H3O+ + Br-
HI + H2O → H3O+ + I-
(nitric acid, sulfuric acid, and perchloric acid are also strong acids)
..where as weak acids only ionize partially..
acetic acid as an example..
C2H3O2H + H2O ⇌ H3O+ + C2H3O2-

∙ 11y agoHI is not the strongest acid. HClO4 is the strongest acid. But HI is the second strongest because Iodine has a large radius and does not hold onto the H+ when it bonds. It wants to get rid of the H+ in a reaction.

∙ 15y agoYes, it is one of the strongest mineral acids known.

∙ 8y agoThe iodide anion has the largest radius of all the halide ions, which means it will dissociate the easiest from the hydrogen ion.

If HBr is a weak base?
No. HBr is a strong acid.
Is HBrO4 a weak acid?
HBr is a strong acid.
What Is HBr a strong acid or a strong base?
It is a strong acid. Hint: if the formula begins with H it is usually an acid.
Is HBrO a base or acid?
HBrO is a weak acid. In solution it partially deprotinates to form BrO- and H+
Is hno3 a monoprotic acid?
No, it is a diprotic acid, the first protolysis is strong, the second is (somewhat) weaker, however also this can be regarded as stong. (miscalculation << 0.3 pH unit)
If HBr is a weak base?
No. HBr is a strong acid.
Is HBrO4 a weak acid?
HBr is a strong acid.
What Is HBr a strong acid or a strong base?
It is a strong acid. Hint: if the formula begins with H it is usually an acid.
Is HBr and NaBr a buffer?
This does not make a buffer because HBr is a STRONG acid, and for a buffer you need a WEAK acid and the salt of the acid.
Is bromine a strong or a weak acid?
Bromine itself is not considered an acid. However, it can react with water to a small degree to form hydrobromic acid (HBr), a strong acid and hypobromous acid (HBrO) a weak acid. Br2 + H2O --> HBr + HBrO
Is HBrO a base or acid?
HBrO is a weak acid. In solution it partially deprotinates to form BrO- and H+
Why is HBR fully dissociated?
because it is a strong acid
Is hno3 a monoprotic acid?
No, it is a diprotic acid, the first protolysis is strong, the second is (somewhat) weaker, however also this can be regarded as stong. (miscalculation << 0.3 pH unit)
Which is the fourth strong acid?
Hydrochloric acid.HClO4 >> HI >> HBr >> HCl >> H2SO4
Is HBr acid?
HBr can be a gas called Hydrogen bromide. When the gas is dissolved in water it dissociates into Br- and H+ ions. The H+ ions make it an acid. This acid is called Hydrobromic acid.
Which is weaker hydrobromic acid or ethanoic acid?
HBr is a strong acid. Ethanoic acid (acetic acid) is a weak acid. So ethanoic acid is weaker.
Give a chemical formula for a strong acid?
Hydrochloric acid: HCl Sulfuric acid: H2SO4 Nitric acid: HNO3 Hydrobromic acid: HBr Perchloric acid: HClO4
