1. Chemical Reactions Lab
Purpose: To observe chemical reactions.
To predict the products of a variety of chemical reactions.
To identify reactions by type.
Reaction 1:
Copper(II) sulfate + zinc 
Reaction 2:
Sodium carbonate + nickel(II) chloride
Reaction 3:
Sodium phosphate + copper(II) sulfate
Reaction 4:
Cobalt(II) nitrate + sodium carbonate
Q) Use the solubility chart to determine the precipitate for each
reaction. Write the name of the precipitate for each reaction.
Reaction 5: Magnesium + oxygen 
Q) How can you make sure oxygen is a reactant in this
reaction?
Reaction 6: Magnesium oxide + water 
Q) Was the product an acid or a base? Is this what you would
expect from this reaction? Explain.
Reaction 7: Zinc + hydrochloric acid 
Q) What gas was formed in this reaction? What evidence
from the reaction do you have to support this?
Reaction 8: Copper(II) carbonate 
Q) What gas was formed in this reaction? What evidence from
the reaction do you have to support this?
Analysis:
1. Write a balanced chemical equation for each reaction. Use your own
paper, and double space in between equations.
2. Provide the state symbol for each.
3. Identify each reaction by type.
4. How were you able to classify each reaction
