HBr is short for Hydrogen Bromide. It's a gas that forms Hydrobromide acid when it comes into contact with the skin or lungs. Hydrobromic acid is an aqueous solution of hydrogen bromide, also called HBr(aq). Salts of Hydrogen Bromide are called Hydrobromide. An example is Arecoline Hydrobromide, or Arecoline HBr.

I bubbled Hydrogen Bromide into freebase arecoline that was dissolved in ethyl chloride. Now I got Arecoline Hydrobromide (Arecoline HBr, ArcoFuel).
