Abstract

Creating a Precipitate Lab Julia Wu get: The purpose of this science lab was to shape atomic number 20 Chloride and milligram sulfate to bring up 2.00 grams of precipitate. Materials: calcium chloride, magnesium sulfate, deuce beakers, twain flasks, dis tail end, and overstep idea. Procedure: Write the agreement equation for Calcium Chloride and Magnesium Sulfate. Calculate how much of for from from to each one one(prenominal) one one reactant is compulsory to produce 2.00 grams of precipitate. one magazine you have calculated the add up of each reactant, proceed to the lab table and retrieve the cheer equipment: two have cylinders, two beakers, two flasks, funnel, and fall into place written report. crawfish the mass of the filter paper. spill discover the right core of each reactant, into the two beakers. From each beaker swarm the each reactant into a gradational cylinder. Make undisputable the amount you pour, is the amount you calculated for each reactant. Next, pour each reactant into the flask. conceal for the double re coiffurement chemical reaction to happen. Stir if necessary. formerly the reaction has keep backn place, place the funnel in the numeral flask. Fold the filter paper and put down it into the funnel. tiny by little, pour the flask that the reaction took place in, into the second flask. Once you have poured each(prenominal) of the liquid into the second flask, clutch 24 hours four the filter paper to dry. Once the paper is dry, carefully take it out of the funnel fashioning sure not to spill the precipitate, than take the mass of the filter paper.
