Write the net ionic equation for the acid-base hydrolysis equilibrium that is established when ammonium bromide is dissolved in water. (Use H3O instead of H .) H2O(l) This solution is ___.

NH₄⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + NH₃(aq)

The solution is acid.

Explanation:

Ammonium bromide → NH₄Br

This is a salt that can dissociates like this:

NH₄Br(aq) →  NH₄⁺(aq) + Br⁻(aq)

NH₄⁺ cation comes from a weak base, the ammonia. So the cation is the conjugate strong acid.

Br⁻ anion comes from a strong acid (HBr), so the anion is the conjugate weak base and in water, it does not make hydrolisis. It does not react.

So the NH₄⁺ is the one that can react to water, realeasing one proton as this equation shows:

NH₄⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + NH₃(aq)

As we give hyrdronium in the medium, the solution is acid.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
