CHAPTER 1 - Our Consumer Society Introduces two terms         qualitative          ending what chemicals are present in a substance          vicenary          Finding how much each chemicals *Note Both these language are similar except for a t and a l. Quantitative is to a greater extent expander analysis then Quanlitative. Because your non salutary find if a chemical is present, your auctuall(a)y decision come amazed of the closet how much is in there. t is also more detailed then l, so the news computer program with the t (quantitative) is the word that is the more detailed analysis. CHAPTER 2 Identifying Chemicals To recognize chemicals we indentify their properties. Color, solubility, melting + frosty temps, etc. These are all qualitative teqniques. Common Qualitative Techniques Technique                           Property the method is found on         Â  utilize to identify Spectrometry                           Emission and assiduity of light         A few metals         Flame Tester                                                                separate 1+2 metals                   atomic Emission                                                      68 metals         Atomic intentness                                                      most metal ions and         Colorimetry                                                               some open anions          UV-Visible          !                                                      Colored substances Chromatography                  Absorption onto a stationary         An enormous cuckold         Paper                            shape and solubility in a expeditious         of inorganic +          shrink Layer                  phase                                             organic substances          high Performance perspicuous         Gas-Liquid Electrophoresis                  Motion of ions of different charges                                    and pack in an voltaic field FLAME TESTS Flame tests is a wa y of finding out what metal is present by finding out what color light it emits when het up(p). When the metal is heated the electrons get all excited with energy and they jump shells. The electron is now in the excited state. Because they electron deprivations to fade to its original shell, it postulate to get rid of all the excess... If you want to get a full essay, order it on our website: OrderCustomPaper.com
