The purpose of this lab activity is to observe various reactions, and write net ionic reactions.
For each reaction that is completed below:
1. Write the full reaction.
2. Write the net ionic reaction (make sure it is balanced).
3. Write observations.
(a) Start with the physical properties of the reactants.
(b) Then describe what you saw occur and how it looks in the end.
Set 1:
Obtain 3 test tubes. Fill one with 2 mL of 0.1 M hydrochloric acid, the second one with 2 mL of 0.10 M solution of copper (II) sulfate, and the third with 2 mL of 0.10 M solution of silver nitrate. Add a few pieces of magnesium turnings to each. Allow them to react while you write your reactions and then observe.
Set 2:
Wash your three test tubes. Fill each with 2 mL of 0.10 M solution of silver nitrate. Add 2 mL of 0.10 M solution of potassium iodide to test tube #1, 2 mL of 0.10 M solution of hydrochloric acid to test tube #2, and a few pieces of copper to test tube #3. Allow them to react while you write your reactions and then observe.
Set 3:
Wash your three test tubes. Fill each with 2 mL of 0.10 M solution of lead (II) nitrate. Add 2 mL of 0.10 M solution of potassium iodide to test tube #1, 2 mL of 0.10 M solution of hydrochloric acid to test tube #2, and a few pieces of zinc to test tube #3. Allow them to react while you write your reactions and then observe. Don’t dump down the sink! Give to me. They contain lead.
Set 4 (As a class): DON'T DO!
An egg is placed in vinegar.
Gummy bear in potassium chlorate.
