3/5/14 3/5/14 Flame Test Purpose In this experiment I will learn how to perform and observe the flame tests of some alkali and alkaline earth metals and be able to identify and unknown chemical by the color of the flame Procedure I placed about 0.5 mL of 8 different chemicals into 8 different places in the 24-well plate. I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame color change

Special Report Plastic Additive: A Techno-Commercial Profile B.G. SAMPAT E-mail: bgsampat@bom3.vsnl.net.in INTRODUCTION Every activity in modern life is influenced by plastics and many depend entirely on plastic products. All these plastic products are made from the essential polymer mixed with a complex blend of materials known collectively as additives. Without additives‚ plastics would not work‚ but with them they can be made safer‚ cleaner‚ tougher and more colourful. Additives cost money

How does the chemical being burned affect the color of fire? Why do you think each fire burns a different color? The colors of the flames are are due to the different chemicals and substances. The bright yellow-orange of most wood fueled flames is because of the sodium‚ and when it’s heated‚ it emits the glow of the fire. The blue in some wood-fueled flames is because of the carbon and hydrogen emit a blue and purple aura. How are the colors produced by a chemical when it burns related to the atomic

be found in a compound. And in order to detect the presence of metals in a compound‚ flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame. Flame test is fast and easy to perform. All the equipment needed for flame test is present in all chemistry laboratories. Solubility is a quantitative term defined
