Period ______ aluminum and copper chloride activity chemistry coleman background: in this lab you will be observing the reaction between copper (ii) materials: beakers glass stirring rod / thermometer 05 m copper (ii) chloride, cucl2 safety glasses (aq)- solution aluminum foil safety: wear safety. Day 1: turning aluminum foil into copper -- applying stoichiometry in lab ( cornerstone #2) objective: swbat determine how many moles of copper should be produced from a measured amount of aluminum foil, and compare this theoretical yield to their actual yield students are directed to record their observations. Buy here: mical- reactions-lab product description exercise 1: reactivity of metals data table 1 observations of chemical reactions with aluminum foil which of the reactants in data table 1 showed evidence of a chemical reaction with the aluminum foil. Note: the following is not a procedural check-list that is contained in the lab handout this is a brief summary of dissolving aluminum foil gravity filtration reactions that complete alum formation crystallization vacuum filtration work in pairs dissolving observe and record changes in the filtrate using a hot plate, heat. Use aluminum foil, salt water, and activated charcoal to construct a simple battery strong enough to power a small motor or light.
Materials 3 small cups full of soil tape, a marker, and 3 sticky notes medium- sized box (such as a shoebox or a storage cube) 12 corn seeds aluminum foil small cookie sheet that fits inside the box (or another sheet of aluminum foil) 1 straw water. Pre-lab questions: write the balanced reaction of al with cucl2 what is the limiting reactant if 05 g al is reacted with 35 g cucl2 take into account cucl2 is a dihydrate when calculating the molecular weight what is the theoretical yield of copper produced by this reaction materials: copper (ii) chloride aluminum foil. Carefully add 10 drops of naoh to the aluminum foil and begin the timer when the first drop hits the foil 4) when there is a noticeable evidence of a hole in the foil, stop the timer another way of knowing that there is a hole is by observing if the chemical solution drips down the test tube record the time 5) using forceps.
Thickness of aluminum foil using radioactive isotope and nuclear scalers, page 1 purdue university students should observe all laboratory safety precautions, including the wearing of appropriate clothing, footwear, and safety goggles 2 obtain the materials listed above, and take them to your lab bench make sure. The goals of this experiment are to practice in the art of observation, the art of questioning, and the development of a better understanding of this process hypothesis: through this experiment, we will learn how candle is working materials: candle note card matches or butane lighter aluminum foil 1l beaker.
Watch aluminum foil disappear as it is added to a green-blue solution of copper(ii ) chloride observe as to the reaction(s) that are occurring and have them write an equation for the reaction(s) they observe lab report including hypothesis, experimental design, results of experimentation, interpretation of the results, and. You must have your procedure approved by your teacher before you begin the lab observations: observe and record as many physical properties of aluminum foil as you can make sure to create a proper observations table with a proper title note: all calculations are shown underneath the table in a subheading called. This experiment illustrates the displacement of copper from copper(ii) sulfate solution using aluminium foil students add aluminium cooking foil to copper(ii) sulfate solution and observe no reaction then sodium chloride is added and dissolved a vigorous displacement reaction occurs and the solution gets very hot ,.
Nh4oh – ammonium hydroxide results observations of chemical reactions with aluminum foil chemical start time initial appearance of chemical initial appearance of foil observations after 5 minutes observations after 3 hours appearance of foil after rinsing agno 3 3:38 am cloudy swirls slightly darkened edges. Observations 2 stir the system until the crystals dissolve record observations 3 loosely roll up a square of aluminum foil, and add the foil to the beaker/contents record observations 4 clean up: pour the contents of the beaker in to the “ copper waster beaker” over by the fume hood rinse the beaker in the sink. This simple activity can be used as a mini-lab, a full lab, or a teacher demonstration students are able to visualize the concept of limiting reagents by performing three reactions between aluminum foil and copper(ii) chloride students can relate observations to mole ratio from the balanced equation. Draw and color what you see from the side part 2 making sedimentary rock procedure a fold the aluminum foil over your three layers of chips b place two –three heavy books over the aluminum foil and leave for 3 minutes c take off the books and observe the chips 4 describe your observations in the space below.
Maximum = 9 (2) observations: copper(ii) chloride is a blue-green solid when placed in water, the crystals turn bright green with a slight blue tinge in the water above the crystals when stirred, the crystals dissolve and form a light blue solution the initial temperature is 22oc the aluminum foil is a.
The “eating away” of the aluminum causing a burning smell and release of heat you could observe and feel the heat from the cup, which proves its an exothermic reaction aluminum reacts with copper(ii) chloride, cucl 2, to form copper metal and aluminum chloride, alcl 3 identify the reactants and the products for the. 1 write a paragraph on your observations in this lab when the aluminum was placed in the copper chloride solution, i was surprised to see how quickly the change occurred immediately it started to rust or turn into a copper color when we added more foil and stirred, the chemical reaction slowed when we added the. The idea is that each lab group will be given a small rectangular piece of aluminum foil, a centimeter ruler, and access to a balance that's all the set-up required a science teacher's dream explain to the class that they will be measuring the thickness of a piece of aluminum foil, but that it cannot be done.
