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.
Do acids react with oxygen?
It depends on the acid. Many acids do, such as acetic acid (CH3CO2H), sulfuric acid (H2SO4), and hypochlorous acid(HClO). But a number of other acids do not contain oxygen, such as hydrocyanic acid (HCN), Hydrochloric acid (HCl), and fluoroboric acid (HBF4)
Why is hydrogen fluoride a weak acid?
Hydrogen fluoride (HF) is considered a weak acid because it only partially ionizes in water. When HF is dissolved in water, it undergoes a partial dissociation into hydrogen ions (H⁺) and fluoride ions (F⁻). The equilibrium reaction for this process can be represented as follows: HF ( � � ) ⇌ H ( � � ) F − ( � � ) HF(aq)⇌H (aq)+F − (aq) In this equation, the double arrow indicates that the reaction is reversible, and not all HF molecules dissociate into ions. The majority of HF molecules remain in molecular form. The reason for the partial dissociation of HF lies in the strength of the bond between hydrogen and fluoride in the HF molecule. The hydrogen-fluorine bond is a strong covalent bond, and it is not easily broken. As a result, only a small fraction of HF molecules dissociate into ions when dissolved in water, making HF a weak acid. In contrast, strong acids, such as hydrochloric acid (HCl) or sulfuric acid (H₂SO₄), completely ionize in water, producing a high concentration of hydrogen ions. The strength of an acid is related to the extent of ionization in water, and weak acids ionize only partially.

Do strong acids always contain oxygen?
No. The haloacids (hydrochloric, hydrobromic, and hydriodic acids) are strong acids that lack oxygen. They have the formulas HCl, HBr, and HI respectively. An example of a strong acid, at about pH 2 would be Hydrochloric Acid (HCl) which is made up of one atom of hydrogen and one atom of chlorine. HCl is a binary (2 atoms) acid (another example would be Hydrosulfuric Acid - H2S) all of which are oxygen-free; however, ternary (3 atoms) acids do contain oxygen. Examples would include Nitric Acid - HNO3 and Chlorous Acid - HClO2 where the O represents oxygen.
