Flame Test Laboratory Report Introduction The purpose of this lab is to observe and identify metallic ions‚ using flame tests. The traditional flame test originated when Robert Bunsen invented the Bunsen burner to test two new alkali metals he and his partner had discovered. “A flame test is an analytic procedure used in chemistry to detect the presence of certain elements‚ primarily metal ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element
Premium Photon Atom Spectroscopy
INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis of Flame Photometry

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the

A company has the ability to enter into a contract‚ can sue and be sued in its own name‚ has the right to own land or property‚ and also enjoy perpetual succession. As a company‚ they have the ability to enter into a contract which meant they can make contract with its own shareholders within the company. Any contract made between company and its members are not illegal due to the principle of separate legal entity. As what we have seen in the case of Saloman v Saloman‚the company can borrow money

Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color
