Lab Report

Ryan Gillis December 14, 2010 Cubs Flame Test for Metals Purpose- The purpose for doing this science research laboratory is to secernate the flammability of mental particles and the tricks they give glum. I have in mind that nearly coats leave behind burn longer than others and with a more wicked color and brightness. Materials- Paper towels, safety gawk, drift burner, potassium process, calcium nitrate, strontium nitrate, copper nitrate, sodium nitrate, barium nitrate, Popsicle sticks, 50 Ml beaker, crucible tongs Procedure- commencement ceremony we got on our safety goggles and aprons. Then we got our burners and crucible tongs. after that we got our paper towels sheets and labeled it with the divers(prenominal) medals we were testing. later that we went and got the Popsicle sticks that were swipeing in the metal particles. This enabled them to soak up the entire metal particle. After that we right away deposit the Popsicle sticks in the flame r ight supra the versed cone and watched what happened. Make sure that you be continuously wretched the Popsicle stick in the flame or it will start to burn. For each(prenominal) metal the scant(p) given prepare out is assorted. Some are brighter than others while others are dark. After each test record your results. After you have success unspoilty put down all of your results you should put your materials away and chuck out of the metals properly.

Data- Stapled on back Results- During this lab we found out a lot about the unalike properties of metals. Sodium nitrate gave release up a bright orange light. Potassium nitrate gave pip a pale and in truth light orange. Calcium nitrate gave mutilate a chromatic color wi! th a slight amount of orange. Barium gave off a very light pale orange. Strontium gave off a bright orange with a little raciness of white. crap gave off a greenish yellow color. unnamed gave off an unusually bright orange. Conclusion- This experiment showed us that these metals are make up of different things because they reacted different to fire and gave off different colors. The reason these different elements...If you want to get a full essay, order it on our website: OrderEssay.net
