In this task, you will carry out the chemical reaction between ammonia and epsom salt: 2nh3 + mgso4 + 2h2o → mg(oh)2 + (nh4)2so4.

look at the three bottles. what evidence is there that a chemical reaction took place?
compare bottles 1 and 2. how do the amounts of the reactants compare? how do the amounts of the products compare? for these two bottles, does the amount of product appear to be proportional to the amount of ammonia used?

compare bottles 2 and 3. how do the amounts of the reactants compare? how do the amounts of the products compare? for these two bottles, does the amount of product appear to be proportional to the amount of ammonia used?

compare your answers in parts b and c. if your answers to those are different explain why.

imagine mixing 1 tablespoon of epsom salt with 2 cups of ammonia. how much precipitate would be produced? describe the amount of precipitate by comparing it with the amount in bottle 1, 2, or 3. explain your prediction.
