After running multiple tests in the three different procedures‚ the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio. Introduction The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine the mole ratio in a reaction by determining the amount of excess reactant‚ amount of product‚ and amount of hydrogen gas produced as well as finding the best research method to determine

Synthesis Procedure 1 -1.0 Introduction A Cobalt-Amine-Halide compound is synthesized from cobalt (II) chloride hexahydrate. An orange-tinted solid is produced and is considered to be unknown since the specific ligand amounts are unknown. By determining the percent composition of various elements and compounds in the unknown‚ its true identity can be predicted. Chloride‚ ammonia‚ and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns

60108 x 68.92558amu .39892 x 70.9247005 average atomic mass = 69.723amu The Mole (Section 3.2) In chemistry‚ we use the counting unit of a mole (mol). This is defined as the amount of particles that are in exactly 12.00 g of the isotope 12C. This number is 6.022 x 1023. Using this same relationship‚ it can be reasoned that 6.022 x 10 23 amu = 1.000 g. Therefore‚ the average mass of one mole of any element in grams is equal to the average atomic weight‚ also called the average
