When stirred, the crystals dissolve and form a light blue solution. Decant When placed in water, the crystals turn bright green with a slight blue tinge in the water above the crystals. In this lab we conducted a number of “mini labs”. ? Subject Science Chemistry Revised Curriculum Keywords aluminum copper chloride chemical chemical reaction BCScTA observation Learning Standards BC Science 9 (2016) Element properties as … When the ammonia was added to the solution, the solution turned into a dark and cloudy blue concoction. Write an investigative question that describes the scientific goals of this experiment. Your answer to number 7 is the number of moles 6. Wear safety goggles. If you know the grams of aluminum to be reacted you should be able to thermometer. Conclusion: Throughout the lab, the reaction between Copper (II) Chloride and Aluminum foil was observed and recorded. graduated cylinder filter paper. By looking at the balanced equation, how many Copper atoms on the Product Also, the aluminum ion in solution may be coordinated with four chloride ions: [AlCl 4] 1-But that isn't the whole story. Chemistry: Aluminum – Copper (II) Chloride Reaction. Is the reaction exothermic or endothermic? 3. of copper and you should have the amount of copper that will come out of this 8 your data table. The Products are Copper Metal and Aluminum Chloride, AlCl3. Multiply your answer to number 6 by the number of atoms of copper you If you watch the solutions color change during the reaction. 2. Results. Procedure 1) Obtain and label a … BE CAREFUL NOT TO LET ANY OF THE BROWN SUBSTANCE GO DOWN THE DRAIN. Copper Chloride & Aluminum Lab. When you put aluminum in copper chloride, the copper together the chloride eats away at the aluminum. 5. your small 50 ml beaker, 1. your notes on how to do Molarity!) Aluminum and Copper Chloride Lab: Limiting Reagent Edition Qualitative Observations: We already noticed that a red precipitate formed, but it is also important to find evidence for the aluminum ionizing in the solution. - Actual grams of brown sub.ê of your Al wire and record on 55.0 grams of aluminum powder is mixed with 75.0 grams of ferric acid, which of the two substance is the limiting reagent? What You want the brown substance to fall into the beaker! … board. grams of brown sub. Add a small amount of copper (II) chloride (about the size of two peas) to the water and stir. as well as inferences . Learn the crucial role of a catalyst as the single-replacement, oxidation–reduction reaction … predict how many grams of a brown substance will be produced by using a side of the reaction? experiment. Is this reaction: Combustion, Single replacement, Double replacement, of your small beaker and record scoopula 13. Copper (II) ions will hydrolyze to produce an excess of hydrogen ions, making the copper (II) chloride solution slightly acidic. This allows reaction with the copper(II) sulfate. Copper (II) chloride (aq) + Aluminum (s) → copper (s) + aluminum chloride … You will look for clues asto which substance was in excess and whichlimited the reaction.Write an investigative question that describes thescientific goals of this experiment. Find the mass Aluminum reacts with copper(II) chloride, CuCl2, to form copper metal and aluminum chloride, AlCl3. you will need to add to the, 15 AGAIN, BE Christopher Wilson Ethan Urbanowitz 7 th period 12/7/2018 Copper (II) and Aluminum Lab Purpose This lab will demonstrate the reaction between aluminum and copper (II) chloride while also refining the skill of making qualitative and quantitative observations. 4. If you put together Copper (II) Chloride, also known as CuCl2 and Aluminum, the sum of it will be Copper Metal and Aluminum Chloride, also known as AlCl3. Copper and Aluminum Lab Procedure: 1. Look at the equation and determine this). When you put aluminum in copper chloride, the copper together the chloride eats away at the aluminum. Grams The equation for the reaction starts like this: CuCl 2 (aq) + Al ??? Observe color changes, production of a gas, formation of solid metallic copper, and a drastic change in temperature. Aluminum foil Safety: Wear … In this lab, students will explore the reaction between aluminum metal and copper (II) chloride. your notes on how to do Molarity!). BE CAREFUL NOT TO LET ANY OF THE BROWN SUBSTANCE GO DOWN THE DRAIN. Then, coil it up into a loose coil with a little left over as a Write out a balanced equation for this reaction. Please tell me if i'm wrong … The ammonia mostly did was turn the copper solution a grayish blue color and thickened the solution. Put your solution in Copper(II) chloride is a blue-green solid. ________g, Mass This means that aluminum must be less dense than the copper chloride solution. ________g, Mass (see your answer to #3), 7. Avoid contact with skin. On day one of the lab, we allowed aluminum to react with copper (II) chloride in a beaker filled with water. Stoichiometry will be used to calculate the limiting reactant, and the percent yield of copper metal produced. The purpose of this lab is to widen the understanding of mole ratios and how they can be applied. got to see how far off you were. This conclusion was confirmed when the Copper (11) Chloride Dihydrate, a blue solution, turned clear after it was heated proving it was limiting reagent. Purpose: Producing solid copper from aluminum metal and copper II chloride. grams of brown sub. Juliet Yengwia Period 3A 10/14/09 LAB REPORT AIM: Observing Physical and Chemical Changes. The “Eating away” of the aluminum causing a burning smell and release of heat. the questions posed to you in the question section. Squirt some water (about 20-30 mL) from your water bottle into your Find the percentage error of your results by using the following formula: Percentage As shown in the equation above, the chlorine broke its bond with the copper, and attached itself to the aluminum. Copper(II) chloride is an irritant. Materials: beakers 0.5 M Copper (II) chloride … Cu +2 (aq) + Zn(s) J Cu(s) + Zn +2 (aq) Equation 5 In order to determine the mass of copper metal produced in reaction 5, it is essential that . There is noticeable burning smell and some faint smoke as a result of the chemical reaction. the beaker.
