Percent Yield of Calcium Carbonate

Purpose:

To determine the theoretical yield, actual yield and percent yield of a reaction producing calcium carbonate.

To determine the limiting reactant of a reaction producing calcium carbonate.

Procedure:

1. Mass between 0.25 and 0.5 grams of sodium carbonate to the hundredth of a gram and record in the appropriate place.
2. Place in a 250 ml beaker.
3. Mass between 0.4 and 0.6 grams of calcium nitrate to the hundredth of a gram and record in the appropriate place.
4. Place the calcium nitrate in the 250 ml beaker containing the sodium carbonate.
5. Place 50ml of distilled water in the 250 ml beaker containing the reactants and mix using a stirring rod. (Use a graduated cylinder to measure distilled water)
6. Filter the precipitate in a funnel with a filter paper inside, and let the contents drip into a clean beaker. (For proper procedure for setting up a filter funnel refer to the diagram below.
7. If some of the products stick to the walls of the container, you may use a water bottle containing distilled water to wash out some of the remaining product into the filter paper.
8. Dry the filter paper in an oven or overnight in a safe place.
