Question

Which of the following equations best represents what happens when hydrogen bromide dissolves in water?

a. 2HBr→Br₂+H.
b. HBr(g)→H(aq)+Br.
c. HBr→H⁺ +Br⁻.
d. HBr(g)+H₂O→Br⁻ +H₃₀.

Answer 1

The dissolution of hydrogen bromide in water is best represented by the reaction that forms bromide ions and hydronium ions, which is HBr(g) + H2O -> Br- + H3O+.

Step-by-step explanation:

The question pertains to the dissolution reaction of hydrogen bromide (HBr) in water. The correct reaction that best represents this process is d. HBr(g) + H2O → Br- + H3O+. When hydrogen bromide gas dissolves in water, it ionizes to form bromide ions (Br-) and hydronium ions (H3O+), as opposed to merely dissociating into hydrogen and bromine atoms or ions.
