You will need to make three solutions:
Calcium Chloride solution: Add 2 tablespoons of vinegar to 1 cup of water, and then add
about 2 tablespoons of calcium chloride (CaCl2).
Sodium Chloride Solution: Add 2 tablespoons of vinegar to 1 cup of water, and then add
about 2 tablespoons of sodium chloride (NaCI).
Baking Soda solution: mix 1 tablespoon baking soda in 1 cup of warm water. If all of the
baking soda dissolves, keep adding more until it stops dissolving. Let the baking soda
solids settle to the bottom of the container, then carefully pour the liquid into a clear
container.
Part B: Precipitation Reactions
Pour some of the baking soda solution into two separate glass containers. Slowly add the
calcium chloride solution to one of the containers and record your results. You should add no
more than 2 tablespoons of the CaCl2 solution. Following the same procedure, add the sodium
chloride solution to the other container. Make sure to take a picture of your precipitate for your
lab submission.
