There are several definitions of acids. The most useful in school-level chemistry is the Lowry-Bronsted definition which says that an acid is a proton donor. The HBr molecule (which you would regard as covalently bonded) breaks up or dissociates into an H+ ion and a Br- ion. So the proton (the H+) can then attach itself to other things, ie it has been donated to something else, for example if it attached to a hydroxide ion OH- it would form water. This is what happens when an acid neutralises an alkali.
In the reaction, HBr donates a proton (H+) to H2O, making HBr the acid and H2O the base. The resulting products are Br- (conjugate base of HBr) and H3O+ (conjugate acid of H2O).
HBr is hydrobromic acid. Simlarly for the other halogens. HF = hydrofluoric acid HCl = hydrochloric acid HI = hydroiodic acid (Careful with the spelling of this one). HAs = hydroastinic acid ( Not characterised).
The chemical formula of hydrobromic acis is HBr.
Hydrobromic Acid
HBr is a gas which when dissolved in water produces Hydrobromic acid. So hydrobromic acid is generally written as HBr but it is actually HBr(aq). It is sometimes also written as H3O+ Br-

Hydrogen Bromine Acid
HBr is an acid. It gives hydroxonium ions and bromide ions when dissolving in water.

Yes, HBr is a strong acid. When it dissolves in water, it releases hydrogen ions (H+) which make it acidic.
Bromine reacts with water to form a mixture of Hydrobromic Acid, HBr, and Hypobromous Acid, HBrO.
HBr is hydrogen bromide.
Hydrobromic acid
If phenolphthalein is added to HBr (hydrobromic acid), which is a strong acid, the phenolphthalein indicator will remain colorless because it only changes color in the presence of a base. Since HBr is an acid, it will not cause the indicator to change color.
