Investigating The Voltage In a Voltaic Cell

Investigating the Voltage in a Voltaic electric cell: The Length of Electrodes Introduction: In chemistry, there is the ability to stray the flow of electrons in a redox reaction. When redox reactions occur, electrons are released at the abode and travels to the cathode. The transportation of electrons causes an electric potential difference. For this study the electrodes go away be analyzed by being in a solution containing metal ions. This experiment tests the effects of uncongenial length electrodes in voltaic cells. A voltmeter will be used to measure the voltage produced and determine if the length of the electrode has each last(predicate) bearing on the heart of volts created. Problem: How do frozen length electrodes affect the voltage in voltaic cells? adventure: If the length of the electrode is long, hence the voltage will be low. Variables: mugwump: Length of Electrodes Dependent: Voltage of Cell Control: submerging and amount of solutions in well (.1M tomentum sulfate and surface sulphate), akin(predicate) sodium chloride bridges (length & concentration), same voltmeter, temperature and printing press. The controlled variables are controlled by victimization the same batch of the solutions, so when the solutions of copper convert, zinc sulfate and saline solutions are make they are made all at once and the same solutions used for each trial.

The salt bridges should be cut to the same coat and then all soaked in the saline solution. The same voltmeter should be used to measure all voltages and the experiment will be conducted at around the sam e time so that the temperature and pressure ! of the environment does not change. Materials: 100 mL .1M horseshit Sulfate (CuSO4? 5 H2O ) 100 mL .1M surface Sulfate (ZnSO4? H2O ) 5 mm x 1 mm Salt Bridges (saline solution and filter paper) 18 mm strip of Zinc o1 mm x 1 mm o2 mm x 1 mm o3 mm x 1 mm 18 mm strips of Copper o1 mm x 1 mm o2 mm x 1 mm o3 mm x 1 mm Voltmeter .5M Saline solution (NaCl and distilled water) Wells ...If you take to get a full essay, order it on our website: OrderCustomPaper.com
