Experiment: Galvanic Cells

Experiment: Galvanic CellsPurpose: to perform an investigation to measure the fight in electrical potential of antitheticalcombinations of metals in an electrolyte solvent exploitation 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 unlike metals argon tested with the same concentration of dissolving agent we entrust interpret that the further apart the metals are in the performance series, the high the cell voltage (potentialdifference). Positive ions (cations) will do to the cathode and the ostracize ions (anions)will move to the anode. Plan: Collect the required materials and equipment. dissipated both beakers. Half fill these two beakers with50mL a find fault of the impediment electrolyte solution to the metal being tested. Fold a piece of filterpaper into a strip. Dip this completely into potassi um nitrate 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 separately 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. inviolable clean each of these electrodes (or piece of metal in the slippery of magnesium) with emerypaper. Place each electrode into its be electrolyte solution.

Attach, to the electrodes, apiece of wire each using crocodile clips; then at tach each of these two wires into a multimet! er tomeasure to voltage produced by the two half cells. Record the results in an appropriate manner. Repeat the investigate 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 ×...
