COPPER SULFATE HYDRATE ANALYSIS [LAB]
Like mentioned before, copper II sulfate dissolves slowly. IT will be a single replacement reaction is a type of redox reaction. Perform a lab involving mass-mass or mass-volume relations, identify the limiting reactant and calculate the mole ratio. Heated copper metal reacts with oxygen to form the black copper oxide. CuCl 4 2-This is a simple example of the formation of a complex ion with a negative charge. Add 2. This is because another reaction does occur in which the gas nitrogen monoxide nitrogen II oxide, NO is Now, set up the galvanic cell.
The initial mass of the copper was 2. Shop Aluminum. Therefore, if we heat this compound, it converts into anhydrous copper sulfate. Its CAS is Teacher Preparation. You will carry out this reaction in the following lab. You will also use Stoichiometry to predict what the theoretical yield of product is and calculate a percent yield. Let the crystals sit. The Aluminum was folded length-wise to make a strip 1 cm x 15 cm. O, will be studied. Determine how much excess remains. Use in chloride environments and other contaminates can cause the potential At the same time, the copper II ions from the solution are reduced to copper metal see second figure below , which causes the blue copper II sulfate solution to become colorless.
Ira Remsen founded the chemistry department at Johns Hopkins University, and founded one of the first centers for chemical research in the United States; saccharin was discovered in his research lab in In the lab, the copper was dissolved in nitrate acid which released a brown smoke and the liquid turned a pure blue. This corresponds to 6. Pre-Lab Questions. If it is not removed with water Aluminum Burner. The archaic name for copper II sulfate is blue vitriol Copper II ions will hydrolyze to produce an excess of hydrogen ions, making the copper II chloride solution slightly acidic.
The object of this experiment is to recover all of the copper with which you began. Copper sulphate pentahydrate contain 5 moles of water per one mole of copper II sulphate. After the copper has dissolved swirl the solution to remove the brown NO2 gas What is in the solution when the reaction is complete? Aluminum would be the limiting reagent Is zinc sulfate a product or reactant? Notice that the sulfate SO 4 2- is not changing during the reaction. A percent recovery will be calculated and sources of loss or gain will be identified. A solution of copper II chloride also known as cupric chloride is added, and the aluminum is oxidized as the copper is reduced. This problem can be eliminated or minimized by replacing the magnesium rod with one made of aluminum or zinc.
An oxidation-reduction reaction occurs where there is a transfer of elections from Aluminum to oxide Copper. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol. The copper oxide can then react with the hydrogen gas to form the copper metal and water. Decant excess solution. For the lab, stoichiometry was used to predict the amount of copper that would be left over. The reaction indicates the ratio between the iron and the copper. Take a piece of aluminium foil approximately the width of the base of the conical flask and approximately 20 cm long. Indeed the reaction is happened, and noticeably quickly too. We combined 2. Introductory Information.
Describe the appearance of the copper II sulfate solution and the aluminum foil before the reaction starts. In its solid, crystal-shaped stone form known as a pentahydrate it's known as blue stone or blue vitriol for its blue 8. Introduction: The purpose of this lab is to find out the number of grams of copper that will be formed from an oxidation reduction reaction when you know the mass of Aluminum that reacted with a known amount of copper 2 sulfate pentahydrate and to compare this to the actual yield of copper. Foaming is usually caused by detergents and similar substances when water has been agitated or aerated as in many faucets. Acids and bases should be at least above pH 3 and below pH 8 before being placed in a sanitary drain.

Using a well plate and the chemical given, determine which reactions will occur between the metals and the solutions. The Golden Penny Lab Experiment: Steve Spangler Science This golden penny lab can be a great science experiment and can be a lesson in learning what pennies are made of. If Note: Set the beaker from Part 1 aside for comparison.
Description: When a ball of aluminum foil is placed in a copper solution with chloride ions, the copper ions are reduced to copper metal and a coating of copper is seen on the surface of the aluminum. The quantities of aluminum and copper sulfate used as reactants will be such that the copper sulfate will be in excess. The water molecules are loosely attached to the salt and can be removed upon heating yielding the anhydrous salt salt without water. After all of the chemical reactions have finished, the final mass of copper was 6. In the first part, you will react a piece of aluminum foil with an excess of copper II sulphate solution to produce copper metal. So aluminium is more reactive than zinc.
Purpose: To determine the of grams of copper that will be produced from an oxidation reduction reaction when you know the mass of aluminum that reacted with a aluminum reacts with copper II ions to form solid copper and aluminum ions. A specific quantity of copper will be transformed through a series of reactions and then recovered as solid copper. Aluminum and steel roofing is commercially available with a painted green patina. Adding sodium chloride jump starts the reaction like a catalyst. We are excited to introduce our new web store coming soon. What kind of reaction is this?
