Flame Test Lab Report
A flame test is conducted when an element is burned and the flame produces a color different the starting flame color. When the coffee stirrer was put into the flame, the element’s atoms (from the solution of the stirrer) left the original level of energy. When the atoms fell back to ground level, they released photons in the form of colored flame. Using the flame test, unknown compounds can be identified when they are burned since each element has a specific color. (Douma, 2008).
The color of the flame produced from the heated atoms can be recorded as a line spectrum which clearly identifies an element. These line spectrums are used by scientists to identify an element, since sometimes it is hard to see what color a heated atom is …show more content…
The controlled variables were the amount of time that the stirrers sat in the solution, the angle at which the stirrer was held over the flame, the distance at which the stirrer was held to the top of the Bunsen burner where the flame is dispensed from, and the time in the flame (when the color stabilized).
When the coffee stirrers were held into the flame for too long, the coffee stirrer burned, which changed the flame to an orange color, from the burnt coffee stirrer. This was true for all of the cations. When the coffee stirrer was held closer to the top of the Bunsen burner where the flame dispensed from, the color of the flame did show quicker than when the stick was held further away from …show more content…
There was no hypothesis since there was no explanation to be proved. Some further experiments to further extend this study is burning different objects to see what cation is in the object. Another experiment may be to see what colors that a combination of cations make. Some improvements may to test the color of the cation being burned by putting the cation in a solid lone state so we are burning the actual element and not the stick with the cation. Another improvement would be to have a larger coffee stirrer so there can be a longer lasting flame, to guarantee the color of the flame.
The flame test concept is taken to the real world in the form of fireworks. The elements are mixed in with a powder that when ignited, explodes. The mixture in the containers of the chemicals and powder puts the atoms of the element or elements into an active state, once again leaving ground state of energy. When the atoms go back to original state of energy, they release photons and brilliant colors just like the flame color in the flame test. (Douma,
