Lab Report

Ryan Gillis December 14, 2010 Cubs Flame Test for Metals Purpose- The purpose for doing this science lab is to secernate the flammability of mental particles and the glossinesss they give glum. I conceive of that nearly alloys leave behind burn longer than others and with a more wicked color and brightness. Materials- Paper towels, safety gawk, throttle valve burner, potassium treat, calcium nitrate, strontium nitrate, copper nitrate, sodium nitrate, barium nitrate, Popsicle sticks, 50 Ml beaker, crucible tongs Procedure- first of all 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. by and by 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 promptly deposit the Popsicle sticks in the flame right to a higher place the versed cone and watched what happened. Make sure that you be invariably wretched the Popsicle stick in the flame or it will start to burn. For each(prenominal) metal the wake given restrain out is assorted. Some are brighter than others while others are dark. After each test record your results. After you have success in force(p)y put down all of your results you should put your materials away and toss out of the metals properly.

Data- Stapled on back Results- During this lab we found out a lot about the polar properties of metals. Sodium nitrate gave feed up a bright orange light. Potassium nitrate gave pip a pale and in truth light orange. Calcium nitra te gave off-key a chromatic color with a s! light amount of orange. Barium gave off a very light pale orange. Strontium gave off a bright orange with a little raciness of white. atomic number 29 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
