Laboratory Experiment This laboratory used a piece of c

cell to determine the relative positions of a series of different

metals in a series of electromotive forces by a qualitative

comparison. A quantitative comparison was also determined by

using voltages emitted by the various metals to calculate

1. The grapefruit was rolled between the hand and a hard surface to increase the electrolytes available in the solution of juice inside the fruit.

2. All the metal strips were cleaned by rubbing them briefly with fine emery paper to scratch them through the oxidized coating. The carbon rod was not cleaned.

3. Two parallel slits were made in the fruit, 2-4 cm apart, to insert the metals into without them touching each other.

4. The positive and negative leads were connected to the multimeter.

5. The multimeter switch was set to the V (volts) area of measurement.

1. The copper and magnesium strips were inserted into the fruit, making sure they did not come in contact with each other.

2. One lead was clipped to each of the metals.

3. If necessary, the leads were switched so that the multimeter read positive.
