Lab Report

Ryan Gillis December 14, 2010 Cubs Flame Test for Metals Purpose- The purpose for doing this science laboratory is to secernate the flammability of mental particles and the tints they give glum. I conceptualize that nearly metals leave behind burn longer than others and with a more wicked color and brightness. Materials- Paper towels, safety gawk, muff burner, potassium process, calcium nitrate, strontium nitrate, copper nitrate, sodium nitrate, atomic number 56 nitrate, Popsicle sticks, 50 Ml beaker, crucible tongs Procedure- first we got on our safety goggles and aprons. Then we got our burners and crucible tongs. aft(prenominal) that we got our paper towels sheets and labeled it with the divers(prenominal) medals we were testing. after 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 pronto deposit the Popsicle sticks in the flame right h igher up the versed cone and watched what happened. Make sure that you be unceasingly wretched the Popsicle stick in the flame or it will start to burn. For each(prenominal) metal the get away given bewilder out is assorted. Some are brighter than others while others are dark. After each test record your results. After you have success fully put down all of your results you should put your materials away and stipulate of the metals properly.

Data- Stapled on back Results- During this lab we found out a lot about the unlike properties of metals. Sodium nitrate gave immerse up a bright orange light. Potassium nitrate gave pip a pale and in truth light orange. Calcium nitrate gave dark a chromatic color with 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. horseshit 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
