Flame Test Laboratory Question: Every time a compound is placed in the fire of a burner, what happens to the color of the flame? Hypothesis: When the compound is positioned in the fire, the flame changes color depending on the substance compound. Once they’re warmed, they gain energy and changed color sometimes. Safety Requirements just for this Lab: Wear goggles always.

If you want to eliminate them to compose in your notebook you may to use a table in the center of the space. When you take a moment remove them then when you operate put them on. Employ aprons. Move back curly hair. No loose clothing.

Close-toed shoes. NO FOOLING ABOUT. It is very important that you DO NOT mix up the nichrome wire hands. History: When chemical compounds are heated, hey gain energy. The electrons in a few of these chemical substances will leap from their earth state electron configuration (such as the electron constructions we have ben drawing to get the elements) to higher levels of energy. As these bad particals fall back in their first positions inside the atom, they emit energy. One type of this energy is lumination energy. This is exactly what you will be watching in this experiment. Materials: Nichrome wire wand Test tubes that contains water Test pipes containing 6M hydrochloric acid as needed to clean line Check tubes that contain: Copper sulfate Potassium sulfate Copper nitrate Potassium nitrate Strontium nitrate Calcium nitrate Copper chloride Strontium chloride Calcium chloride Cobalt chloride Sodium chloride Sodium nitrate Sodium sulfate Barium clroride Calcium nitrate Tirrel burner Matches Goggles Apron Treatment: Work in teams of two At each stand there are two samples and two tirrel burners and matches.

Start off the burner as you have learned to do and have a low green flame with all the inner green flame. Following take the nichrome wire and place in the flame. Noticed the color in order to becomes reddish colored hot. This may not be the color with the flame you are looking for. The flame to observe is a one acquired just as you place it in the flame. Put the wand inside the test pipe with the remedy of the compound, quickly put it in the fire and see its color. Write down the colour and virtually any observations available provided beneath. Do this only three times.

In that case rinse the cable in the drinking water Heat the wire in the flame until it finally has no residue from the chemical substance left. If you have problems inquire your teacher. Return the nichrome line to the normal water test pipe. When this is completed, exchange chemical chemical substance setups with you tablemates. Replicate the procedure for each and every chemical chemical substance. When your table is done with both chemical compounds, go them both clockwise to the next stand. When almost all chemical setups are full, the class can discuss which usually chemical compounds that you would like to observe again.

Analysis: Every single element is made up of different atoms. The heat will help the atoms move around and emit different colors of flame. Only certain factors can be identified by the undressed eye. With others, you are able to identify an element by their hues, or when a metal, by way of a hardness and durability. I do certainly not believe it will be effective mainly because some components might be related in most methods and have you confused. I think if the cable in this laboratory became infected, the outcomes of the flame would be several.

The colors in the flame may not be correct due to the contaminants and chemical compound for the wire. All of the flames don’t have the same color because every single chemical for the wire is unique. It has to have got a boost to a higher energy level. Once they’ve dropped baxck with their first positions, they produce energy. Area of the fire is caused by the exciting metal ions. They may be shown once burned exactly like we performed in class.
