Sequence of Chemical Reactions

science laboratoryoratory #8 The Sequence of Chemical Reactions Drew Selfridge Dave Allen, Lab partner Instructor Yang February 11, 1997 INTRODUCTION This experiment was to find the most amount of shit after it is subjected to a time of reactions. The hair is originally in solid form, but the reactions provide make it into free Cu+2 ions floating in solution. The ions bequeath then be regrouped to form solid cop color at a time again. During this process, however, some of the Cu+2 ions may be lost. The copper will subjected to changes in pH and heat. These steps were liable for the equipment failure and reconstruction of the copper. The percent of copper retrieved will rebound the dexterity with which the reactions were administered. EXPERIMENTAL On an analytical balance, measure the aggregated of the copper piece of music in the vial. Remove approximately 0.35 g into a 250 mL beaker. check the balance and record the mass of th e die harding sort in the vial. In the laboratory touchwood, crash the copper with ~ 3 mL of nitric deadly. Allow the beaker to remain under the hood until the fumes cease. The remaining solution should be blue. Bring the beaker gage to the lab station and add ~ 10 mL of distilled water.

shift the mixture, all the while adding ~ 8 mL of 6M of NaOH to the beaker. Check with litmus paper to ensure that it is slightly basic. convey the beaker with up to one hundred mL mark with distilled water. heat the solution and allow it to dig for 5 minutes. Prepare a squirt bottle with acid water. Filter th e solution and scrub the beaker with the ho! t water. Rinse the trickle cake with hot distilled water. agitate the filter paper into a clean beaker. Add ~ 10 mL of 3M sulfuric acid to the... If you want to get a full essay, order it on our website: OrderCustomPaper.com
