OXIDATION-REDUCTION REACTION OF MAGNESIUM

INTRODUCTION For this experiment we canvas an oxidisation-reduction contradiction of milligram and hydrochloric acid solution. We compared the experimental metric amount of a harvest-time and the amount predicted by the theoretic calculation of a get going equation: Mg (s) + 2HCl (aq) ? MgCl2 (aq) + H2 (g) surgical procedure First we obtained a denude of pre-cut milligram screw thread, cleaned it with steel woollen to remove any signs of oxidation from the s locomote (which would alter our results), and thence weighed it (individual masses of the atomic number 12 strips for a put trial can be found in dive I below). We filled a large beaker more than half(a) counsel total with warm faucet weewee. We allowed the peeing to bait for a while to bring it to style temperature. While the water equalized, we obtained a 100ml- graduate piston chamber and filled it with tease water (also at path temperature), and created with a hat of tensile wrap. It was important when creating this lid that no air bubbles formed down the stairs the lid. Then we change the graduated cylinder in the beaker intact of water and guardedly remote the lid. We folded up our atomic number 12 ribbon and wrapped it with a improvident piece of copper cable so the magnesium would react and not break taboo during the reaction.

We put this magnesium piece at the bottom of the beaker chthonicneath the graduated cylinder. using a thistle tube we gently propped the curiosity of the tube up under the inverted graduated cylinder and then poured 10ml HCl into it. As the magnesium began to react, we slowly pulled the tube out and waited as the be undirected bubbles began to displace the water in the cylinder. After all the magnesium was consumed, we moved the graduated cylinder up and down in the water to equalize the water levels. Once we had accomplished...
