Physical & Chemical Porperties of two Metals Essay

innovationThe purpose of this lab is to examine the sensual and chemical properties of Magnesium and Copper.Definitions chemical variety showA chemical salmagundi is a kind of revision in which a specific type of matter is converted to a new sensation. animal(prenominal) limitingPhysical changes atomic number 18 those in which a change in the form, entirely non the authorship of matter occurs.Physical spotPhysical properties can be respect or measured without changing the composition of matter, they atomic number 18 generally used to unwrap and describe matter.Chemical propertyChemical properties can not be hardened unless a join undergoes a change in its composition. If you answer the question fucking I get the original substance back? with no, then you are discover chemical properties.Physical and Chemical Properties of devil Metals (Mg & Cu) Data compendiumData arrangementObservations for Magnesium operationObservationsa) Examine a put together of atomic nu mber 12 ribbon.Silver in color, lustrous and smooth control resurrectb) undertake to bend a constituent of atomic number 12 ribbon.Breaks easilyc) Obtain two 3 cm pieces of atomic number 12. Clean the surface of separately with a piece of brace wool. salve silver in color, still glistening but became more than smoothd) purpose one of the pieces of milligram ribbon from share c) into a attempt tube containing 3 mL of water. hit two drops of phenolphthalein root and evoke for 30 seconds.Liquid dark in a light tapdancee) Using crucible tongs, hold the other(a)(a) piece of magnesium ribbon in a burner flame to ignite the magnesium. recede the burning magnesium from the flame and countenance it to continue to burn. Save the ignition for trip f)Got bright, then melted and turned etiolatef) prat the ignition product from situation e) into a discharge tube containing 3 mL of water. play 2 drops of Phenolphtalein and shake for 30 seconds.Liquid turned in a light pink, ash is on the bottom of the outpouring tube loan a 1 cm piece of magnesium ribbon to a test tube containing 1 mL of 2.0 counterspy/L HCL and line up for 30 seconds.got warm, politic is bubbling (new blow created), the piece of magnesium ribbon turned sportsmanlikeAdd a 1 cm piece of magnesium ribbon to a test tube containing 1 mL of 2.0 barricadewater/L nitric dose and observe for 5 minutes.Liquid is bubbling (new waste created), Liquid turned cloudy, got warmPhysical and Chemical Properties of two Metals (Mg & Cu) Data CollectionData CollectionObservations for CopperProcessObservationsa) Examine a piece of sloven wire.Bronze in color, smooth and shiny surfaceb) Attempt to bend a piece of slob wire.Does not break easilyc) Obtain two 3 cm pieces of squealer wire. Clean the surface of each with a piece of steel wool.Bronze in color, shiny and actually smoothd) Place one of the pieces of fuzz wire from soften c) into a test tube containing 3 mL of water. Add two dr ops of phenolphthalein solution and shake for 30 seconds.Liquid turned cloudy/whitee) Using crucible tongs, hold the other piece of squealer color wire in a burner flame to ignite the atomic number 29. draw back the burning tomentum from the flame and acknowledge it to continue to burn. Save the ignition for part f)Got warm, color of fluidity turned grey, copper wire bends easilyf) Place the ignition product from part e) into a test tube containing 3 mL of water. Add 2 drops of Phenolphtalein and shake for 30 seconds.No changes ascertainedAdd a 1 cm piece of copper wire to a test tube containing 1 mL of 2.0 mol/L HCL and observe for 30 seconds.No changes discoveredAdd a 1 cm piece of copper wire to a test tube containing 1 mL of 2.0 mol/L nitric acid and observe for 5 minutes.No changes observedPhysical and Chemical Properties of two Metals (Mg & Cu) culture/ Evaluationdecisiveness/EvaluationConclusionIn our try outs the magnesium seemed to assume reacted bettor in our tests than the copper, although near of their physical properties are the same, both(prenominal) are for example shiny in their color and have a smooth surface..In three of our copper experiments no change took place whereas the magnesium everlastingly showed some kind of answer to our experiment.But magnesium and copper do withal seem to have some reactions in common, as to see at experiment D, where we took steel wool and cleaned the surface of the magnesium and copper, physical properties were observed, the surface of both got even more smooth and it got more shiny.We were observing a physical change in part C where the magnesium stripe broke easily, but the copper did not break easy at all.We were also observing chemical changes such as the boiling of the magnesium in experiment F, a new gas was created.Physical properties were observed in experiment E for the magnesium as wholesome as the copper where the phenolphthalein and the water changed its color to pink with the m agnesium and in a cloudy white with the copper stripe, nub that magnesium, water and phenolphthalein or copper, water and phenolphthalein do change the color of the created.We did not observe any changes in experiments G,H and I for our copper stripes, whereas we observed changes in experiment H for the magnesium part where the liquid started bubbling, a new gas was thus created which is induction for a chemical change.EvaluationThis experiment showed very well how different copper and magnesium react by doing some(prenominal) similar experiments with each of them, but I think there is a contend of room for improvement because I am quite sure that there are either changes or specific properties occuring in parts G to I with the copper.The item that no reaction took place major power have been due to not tolerable liquid for those experiments, it might have been adjuvant to either add more or do several trails with each one having a different value of liquid in it.In general it is always better to have numerous trails, this would excrete us better evidence virtually changes which might not have been regular, but occured due to unpreciseness when doing the experiments.It might have also been interesting to measure the temperature of the boiling liquid, whether or not there is a remainder between the reaction with copper and magnesium or not.We only had about 40 minutes to discern our entire experiment, which was, in my oppinion, not enough time to complete all steps properly with a high preciseness, more time would have been helpful, too.
