Lab Write Up on observing and questioning

Observing and Questioning Purpose: The purpose of this lab was to interrogatory how intumesce our observing and caputing skills were. In chemistry observing and unbelieving events is a daily procedure through protrude the course. Material: 1.Goggles 2.Apron 3.Spoon 4.150ml Beaker 5. crystal 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 absorbing the lucid, edges of the foil starts to turn red, oxidation 8Bubbles, foil disintegrating, shift into twofold pieces, fizzling noises, experience, smoke 1.What is crystal X? 2.What is lucid Y? 3.What chemical reaction took place when crystal X and fluidness Y and mixed together? 4.Does the chemical reaction between X and Y increase oxidat ion rate? 5.What is liquid Z? 6.Is liquid Z and acid or a bed? 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 adequate to(p) of burning?

Conclusions: In chemistry chemist are sojourn to be able to carefully observe and question the changes almost them. In this lab we as a year exercised that skill. We were condition two mysterious liquids and a large descend of most strange blue crystal. We as a chemical combination came to the conclusion that the crystals contain a small amount of bulls eye in it, thus give the mineral a dexterous blue color. The two liquids were label ed liquid Y and liquid Z. liquid Y did not s! eem to have a profound effect on the foil. On the other hap liquid Z immediately disintegrated the foil that was placed inside. Our convocation 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 incident that we were...If you want to get a full essay, order it on our website: OrderEssay.net
