Double Displacement Reaction Lab
Chemistry Lab Report
Jeffrey Kenneth Bangero

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 percent 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

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 1.00 g 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

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.
11. When the filtrate stops dripping from the funnel, carefully removed the filter paper from the funnel and place it on a drying oven overnight.
12. After the precipitate had dried, measure the mass of the filter paper and precipitate. Put it on your data table
13. Disposed of the precipitate as instructed by your teacher.

    When making a standard solution anywhere even if it is in a lab or an industry it is important that you have the right type of PPE equipment (personal protective equipment). You will need a lab coat and goggles disposal gloves can also be used but they are not really as necessary as the other two. The first step in making a standard solution in a lab is by putting the weighing boat on a weighting scale and pressing the tare button which will set it to zero. This is done so that when you’re measuring the substance in this case sodium carbonate the beakers mass will not be calculated along with the substance so that you can get the accurate value. After you finish that it is important that when you are putting your substance into the weighing boat that you take it off the weighing boat because sodium carbonate is powder and it is very easy for powder to fall and if it falls while you were putting it into your beaker while it was on the weighting in scale it could change your results and you would have to start again. After you have carefully weighed up the amount of the required substance transfer it into a beaker and them use distilled water to rinse the weighing boat as some particle could have been left inside and add that into the beaker as well. After…

    Weigh a clean, dry weighing bottle and weigh our exactly 1.325g of the pure sodium carbonate into it. Transfer the carbonate to a beaker containing a little hot water (shaking gently as the carbonate comes in contact with the water) and wash the weighing bottle carefully by means of the wash-bottle, allowing the washings to drop into the beaker. Stir gently to ensure dissolution. Then cool to room temperature before proceeding. Smear an almost imperceptible amount of vaseline on the lip of the beaker and pour the solution down a glass rod into a funnel resting in the neck of a clean (but not necessarily dry) 250 cm3 flask. Wash the beaker out with further small quantities of water, pouring all washings down the rod and funnel into the 250 cm3 flask to ensure that no solution is left on the walls of the beaker. It is as well to…

    Transfer the weighed Na2CO3to a clean glass 250 cm3 beaker & add about 100 cm3 of distilled water. Use a clean glass stirring rod to mix the solution until all the sodium carbonate has dissolved. After dissolving, transfer the solution to a 250.00 cm3 volumetric flask. Carefully rinse the beaker and stirring rod and transfer all the washes into the volumetric flask. Take care not to overshoot the graduation mark of the flask. Make the volumetric flask up to approximately 1 cm below the mark on the neck using distilled water from a wash bottle and then using a dropping pipette make up to the mark.…

    After the precipitate has had a chance to settle, collect it by gravity filtration. Wash the collected solid sparingly with cold water. Allow the water to drain from the collected solid. Then transfer the filter paper and precipitate to a paper towel so that excess moisture can be absorbed. Before you leave the lab, place your precipitate (still in its filter paper cone) in a beaker and leave it in your desk to air dry for at least three days. After your precipitate has dried thoroughly, weigh it on the analytical balance.…
