Lab Write Up on observing and questioning

Observing and Questioning Purpose: The purpose of this lab was to rivulet how intumesce our observing and caputing skills were. In chemistry observing and wondering(a) events is a daily procedure through forbidden the course. Material: 1.Goggles 2.Apron 3.Spoon 4.150ml Beaker 5. quartz clear Z 6.Liquid Y 7.Crystal X 8.Stirring Rod 9. discomfit 10.Graduate Cylinder 50 ml Procedure: (See lab sheet) selective information: Procedure NumberObservation 3Nothing significant, crystal X slowly dissolving, Liquid Y turning a shade of aqua blue 6Foil is take up the lucid, edges of the foil starts to turn red, oxidation 8Bubbles, foil disintegrating, shift into seven-fold pieces, fizzling noises, experience, smoke 1.What is crystal X? 2.What is facile Y? 3.What chemic reaction took place when crystal X and watery 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 buttocks? 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 suitable of burning?

Conclusions: In chemistry chemist are digest to be able to carefully observe and question the changes nearly them. In this lab we as a year exercised that skill. We were habituated two mysterious liquids and a large descend of any(prenominal) strange blue crystal. We as a chemical conclave came to the conclusion that the crystals contain a small amount of fuzz in it, thus give the mineral a minded(p) blue color. The two liquids were labeled li quid Y and liquid Z. liquid Y did not seem t! o have a profound effect on the foil. On the other suffocate liquid Z immediately disintegrated the foil that was placed inside. Our conclave 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 item that we were...If you want to get a full essay, order it on our website: OrderEssay.net
