The copper(II) metal complex was prepared by reacting copper(II) chloride and sodium saccharinate together by applying heat. The copper(II) chloride was originally a white solid and the sodium saccharinate was a blue solid. A centigram balance was used to weigh out a 1.01g sample of the sodium saccharinate and a 0.75g sample of the metal salt, copper(II) chloride. Each reactant was placed in separate 50-mL beakers and then dissolved using 10 to 20-mL of deionized water. Once dissolved the reactants were combined into a 250-mL beaker along with a clean stir bar. The solution exhibited a blue color. The original beakers were rinsed with 2 to 3 mL of deionized water. These rinses were then added to the reactant solution; the solution evolved into a light blue color.…show more content…
A light blue precipitate formed along the walls and the bottom of the beaker after being exposed to heat for 15 minutes. After the precipitate was formed the hot plate was turned off and the solution was allowed to cool down until it became warm. Once it was warm the beaker was placed in an ice bath. While waiting for the solution to cool, a vacuum filtration was set up. The solution took around 25 to 30 minutes to cool. Once the solution was cool, we began to isolate the saccharinate salt by pouring the solution into the Büchner funnel. To help further isolate the product we rinsed the precipitate with ice-cold deionized water. Once isolated we dried the product and observed that it was a small-medium sized blue solid. This isolated solid was then weighed and found to have a mass of
