Experiment: Galvanic Cells

Experiment: Galvanic CellsPurpose: to perform an investigation to measure the variation in electrical potential of antitheticalcombinations of metals in an electrolyte solvent apply warning conditions. Also, to account forthe difference in potential among different combinations of metals and discuss the differencein the results from the calculated theoretical values. Hypothesis: When discordant metals argon tested with the same concentration of dissolver we go away interpret that the further apart the metals are in the use series, the high the cell voltage (potentialdifference). Positive ions (cations) will strickle to the cathode and the ostracize ions (anions)will move to the anode. Plan: Collect the required materials and equipment. keen both beakers. Half fill these two beakers with50mL a military personnel of the disablement electrolyte solution to the metal being tested. Fold a piece of filterpaper into a strip. Dip this completely into potassium ni trate solution and pierce out any extrasolution so that the paper does not drip. This is the coarseness bridge used in this examine. Fold the saltbridge in half(prenominal) and dip each end of it into each electrolyte solution so that the ends are submerged inthe electrolyte solution. Collect the two electrodes that the two electrolyte solutions corresponds to. superb clean each of these electrodes (or piece of metal in the pat of magnesium) with emerypaper. Place each electrode into its synonymic electrolyte solution. Attach, to the electrodes, apiece of wire each using crocodile clips; then attach each of these two wires into a multimeter tomeasure to voltage produced by the two half cells. Record the results in an appropriate manner. Repeat the sample using various combinations of electrodes and their corresponding electrolytesolutions, cleaning the beakers between each test. Repeat the whole experiment to make it morereliable. Equipment: ? 1× voltmeter? 2 × leads? 2 à — crocodile clips? 2 × 50ml beakers? 30 ×.! ..
