Make Copper Chloride solution at .5000M ... we first had to determine the safety hazards of the chemical to ensure safety to the people in our lab and in the company. The reaction produces a solution of aluminum chloride and copper solids. Use the masses of CuCl2 2H20 and Al from question #1 to calculate the mass of Cu (theoretical yield) produced. The unbalanced reaction equation is: Al(s) + CuSO4(aq) → Al2(SO4)3(aq) + Cu(s) .... (1) After filtering and washing the copper, you will react the copper metal with nitric acid, producing a … emission of heat identified that a chemical reaction was currently at hand. This is due to the Cu 2+ ion. No longer is the solution made up of copper chloride ions, it is made up of aluminum chloride ions. Lab Prep BEFORE class: Approximately 0.1-0.2 M copper (II) sulfate solution (enough for each group to use about 20 mL) -- add a small spoonful of sodium chloride for every 500 mL of solution (this helps remove the coating on the aluminum foil) Aluminum foil (enough for … Distribute all flashcards reviewing into small sessions. You will be able to monitor the reaction’s progress by evaluating the color change occurring in your beaker. Balance the equation for the reaction between CuCl2.2H20 and Al. Allow the wire to completely react (about fifteen to twenty minutes). Stoichiometry Lab - Aluminum – Copper (II) Chloride Reaction The single replacement reaction of aluminum and copper (II) chloride is a dramatic and exothermic reaction. Place one beaker with.5000M Copper Sulfate into an incubator at 37° C Make sure the Copper Chloride is poured into its beaker while under the fume hood. The strip was coiled loosely to fit into a Copper Chloride solution in a beaker, making sure that the strip is entirely immersed. Lab Prep BEFORE class: Approximately 0.1-0.2 M copper (II) sulfate solution (enough for each group to use about 20 mL) -- add a small spoonful of sodium chloride for every 500 mL of solution (this helps remove the coating on the aluminum foil) Aluminum foil (enough for each group to … In the first part, you will react a piece of aluminum foil with an excess of copper (II) sulphate solution to produce copper metal.
