We are being asked if the solution of NH4BrO will be acidic, basic, or neutral. Ionic salts are made up of positively charged ion (cation) and a negatively charged ion (anion). To determine if the ionic salt would be acidic, basic, or neutral, we need to identify the acidity or basicity of the cation and anion.

For cations:

transition metal

▪ charge of +2 or higheracidic
▪ less than +2 → neutral solution

main group metal
