Description A galvanic cell transforms chemical energy released by a spontaneous redox reaction into electrical energy. Galvanic cells are extremely useful in everyday life, comprising the batteries that power everything from cell phones to cars. In this assignment, you will build a variety of galvanic cells and analyze cell potential data. Instructions Your task is to plan and conduct a simple experiment to test how the concentration of a half-cell electrolyte solution affects the cell potential (voltage) of a galvanic cell. In Step One, you will practice building various galvanic cells. In Step Two, you will analyze the cell potential data of a galvanic cell of your choice and answer your testable question. STEP 1: PRE-EXPERIMENT ACTIVITY Before you begin your data analysis, build the following galvanic cells. After building each cell, complete the following: DRAW A DIAGRAM REPRESENTING EACH CELL. YOUR DIAGRAMS SHOULD INCLUDE THE LABELS OF ALL SPECIES, THE DIRECTION OF ION FLOW FROM THE SALT BRIDGE, AND THE DIRECTION OF ELECTRON FLOW THROUGH THE WIRES. WRITE EACH HALF-CELL REACTION. WRITE THE COMPLETE REDOX REACTION. (((((((((((((((((( The activity will be down in the PDF)))))))))))))))))))))) STEP 2: PLANNING THE EXPERIMENT Choose ONE of the three cells you completed in Step One to study. The results of the experiment are in Step Three. Determine your independent and dependent variables.
