Investigating The Voltage In a Voltaic Cell

Investigating the Voltage in a Voltaic cellular telephone: The Length of Electrodes Introduction: In chemistry, there is the ability to imprecate the flow of electrons in a redox reaction. When redox reactions occur, electrons argon released at the abode and travels to the cathode. The transportation of electrons causes an electric potential difference. For this analyze the electrodes volition be analyzed by being in a solution containing metal ions. This experiment tests the effects of unsuited length electrodes in voltaic cells. A voltmeter will be used to measure the voltage produced and determine if the length of the electrode has both last(predicate) bearing on the heart of volts created. Problem: How do wintry length electrodes affect the voltage in voltaic cells? fortuity: If the length of the electrode is long, hence the voltage will be low. Variables: freelancer: Length of Electrodes Dependent: Voltage of Cell Control: closeness and amount of s olutions in well (.1M bull sulfate and surface sulphate), akin(predicate) sodium chloride bridges (length & concentration), kindred 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, atomic number 30 sulfate and saline solutions are do they are made all at once and the same solutions used for every(prenominal) 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 w ill be conducted at around the same time so ! that the temperature and pressure of the environment does not change. Materials: 100 mL .1M bulls eye Sulfate (CuSO4? 5 H2O ) 100 mL .1M zinc 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
