LAB TITLE: Single Replacement Reaction of Solid Copper with Silver Nitrate
PURPOSE The purpose of this lab is to:
• Observe a single replacement reaction, and
• Calculate the mole ratio of silver (Ag) to copper (Cu) in the reaction
MATERIALS
• Copper wire (30 cm)
• Large test tube
• 250 ml beaker
• Silver nitrate (AgNO3) powder
• Dilute AgNO3 solution
• Distilled water
• Electronic balance
• Glass stir rod
• Watch glass
PRE-LAB DISCUSSION A single replacement reaction occurs when an uncombined element “replaces” another element that is contained in a compound. You will prepare and observe a single replacement reaction in this lab. Your reactants will be copper (Cu) and silver nitrate (AgNO3). You will weigh the reactants and the products carefully to determine the ratio of copper and silver that react – in units of mass (g) and number of atoms (moles). The chemical equation for your reaction looks like this: ___Cu(s) + ___AgNO3 ____??______
PROCEDURE – day 1
1. Obtain a 30 cm length of copper (Cu) wire. Form a coil by wrapping the wire around a large test tube, leaving about 7 cm straight for a handle. Stretch the coil a little so there is some space between the loops. Weigh the copper coil to the nearest 0.01 g and record in your data table.
2. We Labeled a clean and dry 250 ml beaker. Weigh the beaker to the nearest 0.01 g.
3. Weigh the vial of AgNO3 powder provided by Mr. Andrews and weigh to the nearest 0.01 g.
4. We filled the weighed 250 ml beaker with about 100 ml of distilled water. Then added the solid AgNO3 to the water and stirred gently with a solid glass rod until all of the AgNO3 crystals have dissolved. We then Weighed the empty vial.
5. Bend the end of the copper wire so it can be hung over the edge of the beaker with the coil immersed in the AgNO3 solution.
