Investigating the determining characteristics of cations and anions essay sample introduction: the purpose of this lab was to study the specific characteristics of cations and anions, and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. In this experiment, elimination and confirmation tests of various cations and anions were studied in order to use the observations to determine an unknown ionic compound logic trees were developed from the observed behaviors for cations and anions. You can use a flame test to identify a metal or ionic salt persists and is not intensified by an addition of 1% nacl to the dry compound learn something new . In project 2, identification of cations and anions was preformed through a series of confirmation and elimination tests that ultimately led to identifying an unknown ionic compound made of cations and anions.
During this experiment, transposition is performed to remove the cation from the unknown ionic solid, a possible source of interference for the various anion elimination and confirmation tests true to ensure that a centrifuge is properly balanced, place test tubes that are the same size in opposite positions in the centrifuge. There is a couple different ways to determine if a bond is ionic or covalent by definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals so you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals. Science fair project that identifies the nature of ionic and covalent bonds and determines how ionic and covalent compounds differ of a compound what is an ion .
