INTRODUCTION: The purpose of this experiment is to measure the formation constant of the tetraamminecopper(II) ion by colorimetry. Anhydrous copper sulfate (CuSO4) is white‚ which means that it does not absorb light in the visible region of the spectrum. The hydrated copper sulfate (CuSO4 - 5H2O) is blue. The structure of the compound can be represented more accurately as Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. The

Purpose The purpose of this lab was to observe chemical changes which result in different properties. Procedure First all materials needed for experiment were gathered. Using a sanitized scissor‚ all the pipets were cut open at the very top of the pipet. The 96 well plate was used for combining the chemicals to see what the reactions were and the 12 well plate was used for holding the pipets filled with chemicals that had been opened. In column 1 row A of the 96 well plate; two drops of NaHCO3 was

thus presenting a precipitate (s) and the compound Copper Hydroxide(s)—Cu(OH)2. For the third reaction‚ 90 drops of H2SO4 from the pipet was introduced to the Copper Hydroxide(s) to create an acid/base neutral reaction to form Copper Sulfate(aq)—CuSO4(aq). Fourthly‚ lab group 6 slowly added granules of Zinc (Zn) to the Copper Sulfate until the reduction method took place and therefore produced metallic copper(s) within the beaker. The excess
