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?

1. In one step, ammonium chloride (NH4Cl) was added to lower the blood pH. The ammonium ion is what acts as the acid. The chloride ion does not have any acid/base properties. a. Why is the ammonium ion used as the acid source instead of HCl? b. Why is NH4Cl used instead of some other ammonium compound (such as NH4NO3 or NH4I)?

Consider the decomposition of solid ammonium chloride to ammonia andhydrogen chloride gases. What do you predict for the sign of deltaS°? Consider a particulate-level explanation for your prediction. Calculate the value of delta S° for thereaction, and compare it to your prediction. Now consider the decomposition of aqueous ammonium chloride to aqueous ammonia and hydrochloric acid. What doyou predict for the sign of deltaS°? Why? Compare your prediction to the calculated value.
