An aqueous solution of sodium bromide (NaBr) is considered neutral.
When NaBr dissolves in water, it dissociates into sodium ions (Na+) and bromide ions (Br−). Sodium ions do not affect the acidity or basicity of the solution because they come from a strong base, sodium hydroxide (NaOH), and do not hydrolyze. Similarly, bromide ions also come from a strong acid, hydrobromic acid (HBr), and they too do not hydrolyze in water.
Since neither ion reacts with water to produce hydrogen ions (H+) or hydroxide ions (OH−), the pH of the solution remains at around 7, which is the characteristic of a neutral solution. Therefore, an aqueous solution of NaBr does not show acidic or basic properties; it remains neutral.
