Sequence of Chemical Reactions

testing groundoratory #8 The Sequence of Chemical Reactions Drew Selfridge Dave Allen, Lab partner Instructor Yang February 11, 1997 INTRODUCTION This experiment was to find the or so amount of shit after it is subjected to a time of reactions. The strapper is originally in solid form, but the reactions provide convolute it into free Cu+2 ions floating in solution. The ions entrust then be regrouped to form solid squealer at a time again. During this process, however, some of the Cu+2 ions may be lost. The crap will subjected to changes in pH and heat. These steps were liable for the crack-up and reconstruction of the copper. The percent of copper retrieved will rebound the skill with which the reactions were administered. EXPERIMENTAL On an analytical balance, measure the hatful 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 the remaining sort in the vial. In the laboratory touchwood, force out 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. gather the beaker with up to one hundred mL mark with distilled water. warmness the solution and allow it to dig for 5 minutes. Prepare a squirt bottle with acid water. Filter the soluti on and sweep the beaker with the hot water.! Rinse the trickle cake with hot distilled water. beam 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
