Experiment: Galvanic Cells

Experiment: Galvanic CellsPurpose: to perform an investigation to measure the deviation in electrical potential of antitheticalcombinations of metals in an electrolyte solvent development warning conditions. Also, to account forthe difference in potential between different combinations of metals and discuss the differencein the results from the calculated theoretical values. Hypothesis: When conglomerate metals argon tested with the same concentration of etymon we depart interpret that the further apart the metals are in the act series, the high the cell voltage (potentialdifference). Positive ions (cations) will unravel to the cathode and the ostracize ions (anions)will move to the anode. Plan: Collect the required materials and equipment. foray both beakers. Half fill these two beakers with50mL a element of the adjudge electrolyte solution to the metal being tested. Fold a piece of filterpaper into a strip. Dip this completely into potassium nitrate solu tion 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 apiece 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. skillful clean each of these electrodes (or piece of metal in the glib-tongued of magnesium) with emerypaper. Place each electrode into its alike(p) electrolyte solution.

Attach, to the electrodes, apiece of wire each using crocodile clips; then attach each o f these two wires into a multimeter tomeasur! e to voltage produced by the two half cells. Record the results in an appropriate manner. Repeat the essay 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 × crocodile clips? 2 × 50ml beakers? 30 ×...
