Determine The Identity Of Metals Essay, Research Paper

Experiments to find the individuality of metals by analyzing the coloring material of fire when samples of that metal are heated.

The purpose of this experiment was to happen out whether different metals had different reactions when subjected to the fire of the Bunsen burner. This might so let the categorization and designation of certain metals if they have their ain reactions, which will be different coloured fires for this experiment. It was difficult for me to foretell what would happen during the experiment but I was able to compose a hypothesis. I thought that each metal could hold been different colorss such as oranges, blues and leafy vegetables.

Equipment:

* Paddle Pop Stick ( spatula )

* Bunsen Burner

* Evaporating Basins

* Different Salts

* Hydrochloric Acid & # 8211 ; 2 Molar ( HCI )

* Lab Coats & A ; Safety Glasses

Method:

Lab coats and safety spectacless were worn for protection and safety grounds before the experiment was started. All equipment was collected, the Bunsen was ignited

and a little part of Sodium Carbonate was placed in a evaporating basin utilizing a paddle dad stick. The Bunsen burner was so moved so that the fire was straight applied to the salt and the resulting fire coloring material was recorded. This procedure was repeated with Potassium, Copper, Lithium, Strontium and Lead Carbonate every bit good as Colbolt and Manganese Dioxide. All of the fire colorss were recorded for subsequently usage in the consequences. Then a different procedure had used to accomplish a true coloring material fire for Aluminium, Zinc, Iron, Lead, Silver, Tin, Nickel, Calcium, Barium. The procedure was like the first nevertheless before warming, a little bead had to plced on the salt as these had no C atoms unlike the other group of salts. All of the vaporizing dishes were so washed exhaustively after the terminal of this experiment.

Consequences:

Name of Salt or Metal

Flame Colour

Sodium Carbonate ( Na2CO3 )

Orange / Yellow

Potassium Carbonate ( K2CO3 )

White / Yellow / Blue

Copper Carbonate ( CuCO3 )

Green

Lithium Carbonate ( L

i2CO3 )

Green with Red Sparks

Strontium Carbonate ( SCO3 )

Crimson

Manganese Dioxide ( MgCo2 )

Blue / Orange

Colbolt

White Flickers

Tin Pieces ( Sn )

Blue

Lead Carbonate ( PbOC3 )

Green

Nickel ( Ni )

Orange / Green

Calcium ( Ca )

Brick Red

Potassium ( K )

Lilac

Lithium ( Li )

Deep Red

Barium ( Ba )

Apple Green

Aluminium ( Al )

Zinc ( Zn )

Iron ( Fe )

Lead ( Pb )

Silver ( Ag )

Unable to separate with flame trial.

Must precipitate in base.

Decision:

After looking at the consequence of this experiment it was clear that some of the evaporative dishes weren & # 8217 ; t cleaned exhaustively. This was because with some of the samples, two fires were noticed such as a green and a ruddy one together. This job though merely occurred on some of the substances while with most of them the group was able to acquire a individual coloring material alternatively of the open fire.

My hypothesises was largely right nevertheless I have now learnt that there is such thing as ruddy fire. I besides need to alter my hypotheses because every substance had a general coloring material such as green, bluish or ruddy. Alternatively many had more specific colorss such as ruby and lilac. After researching why certain substances react to do different coloring material fires I found out that the heat from the fire affects the negatrons in each atom of the substance. When this happens there is a reaction and the energy is turned into seeable visible radiation but when the fire is removed, the atoms regained their original province. I understand that the coloring material of the fire truly tells how much energy is available to each atom and how much is being used. This fundamentally means that the fire coloring material distinguishes the atomic construction and the wavelengths of Electromagnetic Radiation ( seeable coloring material is apart of this ) given off by the substance. I believe the experiment does non necessitate to be done once more because the consequences were reasonably accurate nevertheless they weren & # 8217 ; t every bit good as I would hold expected them to be.
