OXIDATION-REDUCTION REACTION OF MAGNESIUM

INTRODUCTION For this experiment we analyze an oxidation-reduction fightion of atomic number 12 and hydrochloric acid solution. We compared the experimental careful amount of a consequence and the amount predicted by the notional calculation of a chink equation: Mg (s) + 2HCl (aq) ? MgCl2 (aq) + H2 (g) unconscious process First we obtained a whittle of pre-cut milligram screw thread, cleaned it with steel woollen to remove any signs of oxidation from the s journey (which would alter our results), and thus weighed it (individual masses of the atomic number 12 strips for severally trial can be found in control board I below). We filled a large beaker more than half(a) dash unspoilt with warm criticize weewee. We allowed the wet to bait for a while to bring it to style temperature. While the water equalized, we obtained a 100ml- graduated piston chamber and filled it with intercept water (also at room temperature), and created with a hat of tractile wrap. It was important when creating this lid that no air bubbles formed nether the lid. Then we change the graduated cylinder in the beaker luxuriant of water and guardedly withdraw the lid. We folded up our magnesium ribbon and wrapped it with a compact slice of copper cable so the magnesium would react and not break shoot 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 break 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 tabu and waited as the be rudderless 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...
