1. ethylamine and ammonium chloride
2. citric acid litium propanoate
3. methylamine and methylammonium
What is the identity of the two species in each set (strong acid/strong base/weak acid/weak base/salt/other) and explain your reasoning.
2) Identify if there is anything in common between the two species in each set and underline that portion.
3) How do you think the two species in each set are related to each other? Justify your answer.
4) If there is a weak acid or a weak base present (NOT a significant conjugate acid or a significant conjugate base)? If there is write out the equation relating the two species in each set (HINT: think about writing an equation for the dissociation of the weak acid or the weak base).
5) If applicable, label the species your equation as a weak acid and its conjugate base or a weak base and its conjugate acid.
6) Determine the Ka for the acid species (if you are dealing with a weak base how could you possibly find a Ka for the acid species in the equation?)
7) Could this mixture possibly be a buffer? Why?
