Aluminum + Copper Chloride Lab In this lab we tested on how much amount of Aluminum, Copper Chloride, and water to balance each other out. (Check This is because according to the reactivity of metals, aluminium is more reactive than copper and so it displaces copper from a solution of copper chloride. Take the temperature of the water / copper (II) chloride solution and write down any qualitative observations that you can. A single replacement reaction is a type of reaction where the more reactive metal replaces the less reactive metal dissolved in the solution. experiment. your notes on how to do Molarity!). Do not copy the questions, but show all work! When you put aluminum in copper chloride, the copper together the chloride eats away at the aluminum. aluminum wire used up in this reaction into moles coil to remove the brown substance so it falls into the 150 ml beaker. This means that aluminum must be less dense than the copper chloride solution. Write a word equation for the reaction based in the above statement? 12.

Introduction For this lab, we will be reacting copper (II) chloride with aluminum. of Al wire after it was dipped in Copper (II) Chloride solution, Mass in water. this also into the sink. Using your water bottle, squirt a strong stream of water on the You want the brown substance to fall into the beaker! The equation for the reaction starts like this: CuCl 2 (aq) + Al ??? your small 50 ml beaker, 1. CAREFUL NOT TO BREATHE THE FUMES PRODUCED The wire will be coated with a brown The balanced equation for the reaction is 3CuCl2 + 2Al => 2AlCl3 + 3Cu, where Cu symbolizes copper, Cl symbolizes chlorine and Al symbolizes aluminum. There is noticeable burning smell and some faint smoke as a … Foiled Again — Aluminum Loses to Copper A Redox Reaction Introduction Watch aluminum foil disappear as it is added to a green-blue solution of copper(II) chloride. The equation for the reaction is: 3 CuCl2 (aq) + 2 Al (s)( 3 Cu (s) + 2 AlCl3 (aq) Hypothesis: Materials: Beaker.5 M CuCl2 solution . It was seen in the reaction that the reactants formed Aluminum Chloride and Copper. Goggles must be worn at all times. 4. Write out a balanced equation for this reaction. During the reaction between copper (II) chloride and aluminum, the aluminum dissolves to create a solution with aluminum ions with a +3 charge and copper metal. 6. Purpose: Observe a chemical reaction and identify the indications of a chemical change. 7. What happens when ammonia is added to the Aluminum and Copper Chloride solution? You will look for clues as to which substance was in excess and which limited the reaction. Thus it is custom to name the compound by stating the Metal first and the Non-Metal second, in its ion name (ie Chloride not Chlorine) When the aluminum is placed in the solution, it is clear that it does not sink. We believe that copper metal and aluminum chloride will be the products because single displacement happens a lot when copper is … There is noticeable burning smell and some faint smoke as a result of the chemical reaction. A multitude of factors indicated that a reaction was occurring and some of them included a temperature change, the formation of bubbles, and the formation of precipitate. 6. of Al wire after it was dipped in Copper (II) Chloride solution Dip the coil into the Copper (II) Chloride solution and allow it to Materials / Equipment:250 mL beaker. have on the reactant side. When we put these two reactants together, we believe that copper metal and aluminum chloride will be the products. of your small beaker and record You may also use rubber gloves and coax the brown stuff off the wire and into Chemistry: Aluminum – Copper (II) Chloride Reaction. 2. You will look for clues as to which substance was in excess and which limited the reaction. What eventually happens when you put Aluminum in Copper Chloride? Write the equation using formulas for the reactants and products? Avoid contact with skin. An exothermic reaction is when the reaction causes a releasing of heat. Add a small amount of copper (II) chloride (about the size of two peas) to the water and stir. In this lab experiment, you will react copper (ll) chloride and aluminum. Synthesis or Decomposition? This reaction was exothermic because when we held the cup in our hands it was very warm. Copper(II) chloride is a blue-green solid. Make the solution of Copper (II) chloride as specified in the pre-lab, 5. your notes on how to do Molarity!) Stoichiometry will be used to calculate the limiting reactant, and the percent yield of copper metal produced. Answer: Aluminium reacts with copper chloride to form the copper metal and aluminium chloride. It is also evident that the reaction was an exothermic one. Wear safety goggles. Anyone knows where I can search/create a molecule model out of ball and stick from the internet? Copper II Chloride + Aluminum = Copper + Aluminum III Chloride 3(CuCl2) + 2(Al) = 3(Cu) + 2(AlCl3) Three Copper Chloride + Two Aluminum = Three Copper + Two Aluminum III Chloride.

Pre-Lab:  We placed the Copper Chloride … If you know the grams of aluminum to be reacted you should be able to Copper (II) ions will hydrolyze to produce an excess of hydrogen ions, making the copper (II) chloride solution slightly acidic. Determine the mass Observe color changes, production of a gas, formation of solid metallic copper, and a drastic change in temperature. Answers. During this lab, we tested how much aluminum would need to be added to a solution of copper chloride to become balanced. got to see how far off you were. Also, the aluminum ion in solution may be coordinated with four chloride ions: [AlCl 4] 1-But that isn't the whole story. Other catalysts that catalyze this reaction include sodium bromide, potassium chloride, magnesium chloride, and hydrochloric acid solution. Find the mass When placed in water, the crystals turn bright green with a slight blue tinge in the water above the crystals. Following that, 10 mL of ammonia was added. the reaction from the mass of the original Aluminum wire. This is an example of single displacement. WEAR YOUR GOGGLES TO AVOID SPLASHING INTO YOUR EYES. The solution after the reaction was quite different than before. copper(II) chloride dihydrate, CuCl 2 • 2H 2 O aluminum foil, 8cm x 8cm additional chemicals for step 5 SAFETY In this lab, the solution you are working with may become quite hot following the addition of aluminum foil.

Remind students what copper looks like, so that they know what they are looking for. The ammonia mostly did was turn the copper solution a grayish blue color and thickened the solution. Aluminum and Copper (II) Chloride Lab Purpose: By reacting aluminum with copper (II) chloride, you will make a reaction. Make sure thatyour question applies to any of Copper (II) Chloride to be added to 15 mL of water Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. Aluminum reacts with copper(II) chloride, CuCl2, to form copper metal and aluminum chloride, AlCl3. Make sure that your question applies to … 11. The “Eating away” of the aluminum causing a burning smell and release of heat. See drawing on front Predicted of Beaker & Brown Substance after heating/drying/cooling _______g, Mass When copper chloride and aluminum react together, the aluminum erodes into this rusty, brown dust. Is this reaction: Combustion, Single replacement, Double replacement, During the control reaction 50 mL of water was added to 2 G of copper chloride. This conclusion was confirmed when the Copper (11) Chloride Dihydrate, a blue solution, turned clear after it was heated proving it was limiting reagent.
