Task 1Changing the Amount of AmmoniaIn this task, you will carry out the chemical reaction between ammonia and Epsom salt:2NH3 + MgSO4 + 2H2O → Mg(OH)2 + (NH4)2SO4.You’ll use varying amounts of ammonia to see how the amount of a reactant affects the amount of product.You’ll need these materials:safety gogglesprotective glovesapron3 identical empty disposable water bottles, about 16.9 fluid ounces eachpermanent markerwaterEpsom salt (3 tablespoons)tablespoon measure-cup measureammonia (1 to 2 cups)To begin the experiment, follow these steps. Use this diagram to help you work through the steps:Label the three bottles with the numbers 1 through 3 using the permanent marker.Add 1 tablespoon of Epsom salt to each bottle.Add the following amounts of water to each bottle:bottle 1: cupbottle 2: cup + 1 tablespoonbottle 3: 1 tablespoonThe amounts are different so that the total volume of liquid in each bottle will be the same after the ammonia is added.Add the following amounts of ammonia to each bottle:bottle 1: 1 tablespoonbottle 2: cupbottle 3: cupCap each bottle tightly.Rinse the outsides of the bottles to remove any ammonia that may have spilled onto them.Swirl the bottles to dissolve the Epsom salt.Let the bottles sit overnight, or for at least 8 hours.If solids end up floating on the surfaces of the solutions, tap or gently shake the bottles until the solids sink to the bottom. Wait several minutes for the solids to collect at the bottom of the bottles.Part ALook at the three bottles. What evidence is there that a chemical reaction took place?Part BCompare 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?Part CCompare 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?Part DCompare your answers in parts B and C. If your answers to those questions are different, explain why they’re different.Part EImagine 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.Task 2Changing the Amount of Epsom SaltIn this task, you will carry out the chemical reaction between Epsom salt and ammonia:2NH3 + MgSO4 + 2H2O → Mg(OH)2 + (NH4)2SO4.This time, you’ll use varying amounts of Epsom salt to see how the amount of a reactant affects the amount of product.You’ll need these materials:safety gogglesprotective glovesapron3 identical empty disposable water bottles, about 16.9 fluid ounces eachpermanent markerEpsom salt (8.5 tablespoons)tablespoon measure and -tablespoon measure (or a -teaspoon measure; note that teaspoons equals tablespoon)-cup measurewaterammonia (1 cup)To begin the experiment, follow these steps. Use this diagram to help you work through the steps:Label the three bottles with the numbers 1 through 3 using the permanent marker.Add the following amounts of Epsom salt to each bottle.bottle 1: tablespoonbottle 2: 2 tablespoonsbottle 3: 6 tablespoonsAdd cup of water to each bottle.Add cup of ammonia to each bottle.Cap each bottle tightly.Rinse the outsides of the bottles to remove any ammonia that may have spilled onto them.Swirl the bottles to dissolve the Epsom salt.Let the bottles sit overnight, or for at least 8 hours.If solids end up floating on the surfaces of the solutions, tap or gently shake the bottles until the solids sink to the bottom. Wait several minutes for the solids to collect at the bottom of the bottles.  Part ACompare 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 Epsom salt used?Part BCompare 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 Epsom salt used?Part CCompare your answers from parts A and B. If your answers to those questions are different, explain why they’re different.Part DImagine mixing 10 tablespoons of Epsom salt with cup 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.Part EIn task 1, you varied the amount of ammonia used in the reaction. In task 2, you varied the amount of Epsom salt. Combining the results of these two tasks, what can you conclude about the amount of product formed by two reactants? 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? appeared first on Accredited Research Writers
