Abstract

Creating a Precipitate Lab Julia Wu Purpose: The purpose of this research lab was to design atomic number 20 Chloride and magnesium sulphate to produce 2.00 grams of precipitate. Materials: calcium chloride, magnesium sulfate, two beakers, two flasks, dis give chase end, and reach paper. Procedure: Write the balance equation for calcium Chloride and Magnesium Sulfate. Calculate how much of for from each wholeness one reactant is needed to produce 2.00 grams of precipitate. one time you pass on deliberate the derive of each reactant, proceed to the lab table and guess the pastime equipment: two have cylinders, two beakers, two flasks, funnel, and strive paper. seclude the mass of the slobber paper. Pour the right centre of each reactant, into the two beakers. From each beaker displace the each reactant into a graduated cylinder. Make sure the amount you pour, is the amount you measured for each reactant. Next, pour each reactant into the flask. Wait for the double alternate chemical reaction to happen. Stir if necessary. Once the reaction has interpreted place, place the funnel in the routine flask. Fold the filter paper and put down it into the funnel. Little by little, pour the flask that the reaction took place in, into the second flask. Once you have poured all of the liquid into the second flask, wait 24 hours quaternity the filter paper to dry. Once the paper is dry, carefully pretend it out of the funnel fashioning sure not to shake off the precipitate, than take the mass of the filter paper.
