ABSTRACT
The Copper Reactions experiment was demonstrate by adding the reagents like 16M HNO3, Distilled water, 6M NaOH, 6M H2SO4, Acetone, Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory techniques such as method of separation involving filtration, sedimentation, decantation and extraction. While different reaction were also observe and tallied until the recovered copper was weight and the percentage yield was calculated from the formula:
Percentage Yield = Mass of recovered copper/ actual yield mass of copper wire(Theoretical yield) X 100
The Percentage Yield of the experiment was 87.63%
INTRODUCTION All chemicals reactions occurring within test tube, industrial reactors, or nature, can be described by reaction equations. Knowing the skeletal reaction equation, the reactants and the product are also known, but for quantitative prediction, the reaction equation needs to be balance. A balanced equation is an equation or a chemical reaction in which the number for atoms for each element in the reaction and the total charge are the same for both the reactants and the products. From the balance equations, the mole relationship can be figured out. The amount of product produced from a given amount of reactants based on the balance chemical equations is referred to as the theoretical yield. The theoretical yield is based on the stoichiometry of the reactions and ideal conditionsin which starting material is consumed completely, undesired side reactions do not occur, and there are no losses in the work-up procedure.
