Introduction

CHEMISTRY LAB REPORT The Reactivity Series for the Common Metals Liliana Ospina Chemistry Department LAB REPORT Aim To see if a common metal is reactive or strong enough to replace/push out/displace another common metal from its liquid compound. Hypothesis My prediction will be: the most reactive metal shown by the reactivity series will show if the metal can displace or not the metal in the compound. For example my hypothesis in a reaction of Mg and Pb is that; Mg being a more reactive metal in the reactivity series will displace Pb, a least reactive metal in the series. Equipment 1. A chart with spaces big enough to proceed with the reaction. With the names of each different metals. For obvious reasons put an x from the top left corner to the inferior left corner. 2. A glass bigger than the chart for the paper for protection of it. 3. Each solid metal and metal compound for the reaction: Solid Metals: Magnesium (4), Copper(4), Iron(4), Zinc(4), Lead(4). Liquid Metal Compounds: Copper Sulphate, Iron Chloride, Magnesium Sulphate, Zinc Nitrate, Lead Nitrate. 4. A teat pipette. ...read more.

Conclusion

� The other possible way, could be that the metals weren't very clean before we tested them, and so this could have altered and prevented a reaction in Lead. Evaluation In general we did a great effort with my teammate in the lab, we applied exactly two drops of the metal compound to the metal solid, tried every metal to be clean , but unfortunately we needed machinery to polish every single metal but we did not had it, we just had to do our best at trying to polish them. Another problem we did had, was to handle the spaces and the arrangement of the metals within their boxes in the lab; well we applied a small square to each experiment, we frequently had the metal compound spreading into other boxes, damaging the fair results of the other experiments. One solution could be to apply bigger spaces and arrange each metal at the center of its box. ?? ?? ?? ??
