Experiment 32 Prelaboratory Assignment Galvanic Cells, the Nernst Equation Desk No.- 1. In a galvanic cell, a. reduction occurs at the (name of electrode b. the anode is the (sign) electrode c.anions ow in solution toward the (nane of electrode) d. electrons ow from the (name of electrode) to (name of electrode) 2. a. What is the purpose of a salt bridge? Explain. b. How is the salt bridge prepared in this experiment? 3. Experimental Procedure, Part C.1. A 1-mL pipet is used to transfer 1.0 mL of a 0.10 M CusO, solution to a 100-mL volumetric ask. The volumetric ask is then lled to the mark with deionized water. What is the molar concentration of the diluted solution? Show calculations expressing the concentration with the correct number of signi cant guers 4. Refer to Figure 32.2 and equations 32.8 and 32.9. a. What is the value of the cell constant? b. What is the [Cu2′] if the measured cell potential is 0.96 V? e. What should be the cell potential if the [Cu] is 1.0 x 10 mol/L? Experiment 32 357
