Patronage Jeffrey Kenneth Bangers Introduction Firstly we calculated the mass of the beaker and then we put the assigned grams of sodium carbonate and calcium chloride.

Then we add 50 ml of distilled water to each substance, sodium carbonate dissolved faster than calcium carbonate. After we mixed both sodium carbonate and calcium chloride and they form a solid precipitate. Then we poured it a funnel with a filter paper to get the solid precipitate.

Purpose The purposed of the lab is to lets us student know if we know how calculate the recent yield of a double displacement reaction while using the grams that we get from our lab. Objectives We need to know the solid precipitate that had been formed in the reaction Also we need to know which one is limiting and excess reactant We need to know the percentage yield of the precipitate in grams Materials 2.

3. 4. 6. 7. 8.

9. 2. 00 g of sodium carbonate Distilled water 1. 00 g of calcium carbonate Graduated cylinder Two of 250 ml beaker Waterproof grease marker Electronic balance, accurate for two decimal places Stirring rod

Filter paper Funnel Erlenmeyer flask Wash bottle with distilled water Drying oven Procedure Get two 250 ml beaker and label them using the reactant solutions Copy the data table in the textbook to your notebook , measure the masses the empty beaker and then record it to your data table Put 2. 00 g of sodium carbonate and place it to the labeled beaker.

Then put 50 ml of distilled water on the beaker with sodium carbonate. Use a stirring rod to stir it and then we you removed it rinse it properly so that you do not lose the reactant. Put 1. 0 of calcium carbonate and place it to the labeled beaker. Then record the mass and after put 50 ml of distilled water to the beaker.

Stir it to dissolve the solid material. Then to the same thing in step 3 when removing the stirring rod. When both solids have dissolved, slowly pour the entire thing of the sodium carbonate beaker and while doing it also stir it constantly. Observe the changes and record it. When the reaction is completed, label a piece of filter paper. The measured the mass of the filter paper and recorded it to you data table.

Set up the funnel, filter paper, and flask.

Gently swirl the reaction beaker to suspend the precipitate. Slowly pour the entire contents, a portioned at a time into the filter paper. Rinse the reaction beaker several times with distilled water and then pour it to filter paper to collect all the precipitate. 10.

Rinse the precipitate on the filter paper with more distilled water from the wash bottle to be sure that all the dissolved materials have been removed. 1 1 . When the filtrate stops dripping from the funnel, carefully removed the filter paper from the funnel and place it on a drying oven overnight. 2 Eater the precipitate had dried, measure the mass to the tilter paper and precipitate. Put it on your data table 13.

Disposed of the precipitate as instructed by your teacher. Prefab Questions Double displacement is when the two compounds switch to form a new compound. 2. The balance chemical equation in this investigation is An CO + IAC = enact + coco 2 3 Firstly, if the beaker with the solution was spilled.

Secondly, if all solution wasn’t remote Veda from the beaker. Lastly, if the filter paper wasn’t dried up properly.
