Lab Write Up on observing and questioning

Observing and Questioning Purpose: The purpose of this lab was to prove how intumesce our observing and caputing skills were. In chemistry observing and oppugn events is a daily procedure through off the course. Material: 1.Goggles 2.Apron 3.Spoon 4.150ml Beaker 5. quartz glass clear Z 6.Liquid Y 7.Crystal X 8.Stirring Rod 9. forget 10.Graduate Cylinder 50 ml Procedure: (See lab sheet) information: Procedure NumberObservation 3Nothing significant, crystal X slowly dissolving, Liquid Y turning a shade of aqua blue 6Foil is engrossing the lucid, edges of the foil starts to turn red, oxidation 8Bubbles, foil disintegrating, shift into multiplex pieces, fizzling noises, experience, smoke 1.What is crystal X? 2.What is fluent Y? 3.What chemical reaction took place when crystal X and runniness Y and mixed together? 4.Does the chemical reaction between X and Y increase oxidation rate? 5.What is liquid Z? 6.Is liquid Z and acid or a skunk? 7.Does crystal X contain fuzz? 8.How strong is liquid Z on the pH scale? 9.Are the fumes that came out of liquid X toxic? 10.What else is liquid Z able of burning?

Conclusions: In chemistry chemist are forestall to be able to carefully observe and question the changes well-nigh them. In this lab we as a year exercised that skill. We were inclined two mysterious liquids and a large descend of whatever strange blue crystal. We as a chemical cabal came to the conclusion that the crystals contain a small amount of slovenly person in it, thus give the mineral a pertinent blue color. The two liquids were labeled liquid Y and liquid Z. liquid Y did not seem to have a profound! effect on the foil. On the other work liquid Z immediately disintegrated the foil that was placed inside. Our separate once again came to the conclusion that liquid Z was in incident and hydrochloric acid, the very same acid that is found in the human stomach. However, we were prevented in answering a few of our questions. The accompaniment that we were...If you want to get a full essay, order it on our website: OrderEssay.net
