Write a balanced equation for the proton transfer reaction between hydrofluoric acid (HF) and ammonia (NH₃). Identify each conjugate acid-base pair, and rewrite the equilibrium arrows to indicate if the forward or reverse reaction is favored.

Which of the following bases will have the weakest conjugate acid?

Which of the following aqueous species will contain mostly reactants?

Determine [OH^–] in each base solution. If the base is weak, indicate the value that [OH^–] is less than.

Predict the direction of the following reaction:

HC₂H₃O₂ (aq)  +  H₂O (liq)  ______________   H₃O⁺ (aq)  +  C₂H₃O₂^– (aq)
