Chemical Reactions Lab
I. Purpose: To observe chemical reactions.
To predict the products of a variety of chemical reactions.
To identify reactions by type.
II. Safety: Goggles must be worn at all times during this lab.
Keep test tubes pointed away from people. Never look down the mouth of a
test tube.
III. Procedure: Perform each of the following reactions. In the observation section, list
the color and state symbol for each reactant and each product. Write a balanced chemical
equation for each reaction and identify what type of reaction took place.
Reaction 1: Sodium carbonate + nickel(II) chloride
Reaction 2: Sodium phosphate + copper(II) sulfate
Reaction 3: Cobalt(II) nitrate + sodium carbonate
1. Make solutions of each reactant by placing a few crystals of the salt into
separate small test tube and adding approximately 3mL of dH2O. Shake to
dissolve the crystals. Observe and record properties of the reactants.
2. Pour the two reactant solutions together and allow them to react.
3. Place the test tube into the test tube rack and make your final observations at
the end of the laboratory.
Q) Use the solubility chart to determine the precipitate for each reaction.
Write the name of the precipitate for each reaction.
