General Chemistry 2 Equilibrium Equation

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. C₃H₇NH₃Br

Answer 1

The salt C₃H₇NH₃Br is the result of the reaction between a weak base (C₃H₇NH₂) and a strong acid (HBr).

C₃H₇NH₂ + HBr ==> C₃H₇NH₃⁺ + Br^-

Thus, when dissolved in water, the solution will be acidic.

C₃H₇NH₃⁺_(aq) + H₂O(l) ==>C₃H₇NH₂(aq) + H⁺(aq)
