Question

determine if the following salt is neutral, acidic or basic. if acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. if neutral, simply write only nr. be sure to include the proper phases for all species within the reaction. nh₄br

Explanation:

Step1: Analyze the salt components

\(NH_4Br\) dissociates into \(NH_4^+\) (ammonium ion) and \(Br^-\) (bromide ion) in aqueous solution. \(Br^-\) is the conjugate base of a strong acid (\(HBr\)), so it does not hydrolyze. \(NH_4^+\) is the conjugate acid of a weak base (\(NH_3\)), so it will hydrolyze.

Step2: Write the hydrolysis equation

The hydrolysis of \(NH_4^+\) in water is given by the equation:

$$NH_4^+(aq)+H_2O(l) ightleftharpoons NH_3(aq)+H_3O^+(aq)$$

Since \(H_3O^+\) (hydronium ion) is produced, the solution will be acidic.

Answer:

Acidic, \(NH_4^+(aq)+H_2O(l)
ightleftharpoons NH_3(aq)+H_3O^+(aq)\)
