Investigating The Voltage In a Voltaic Cell

Investigating the Voltage in a Voltaic mobile phone: The Length of Electrodes Introduction: In chemistry, there is the ability to blow the flow of electrons in a redox reaction. When redox reactions occur, electrons atomic number 18 released at the abode and travels to the cathode. The transportation of electrons causes an electric potential difference. For this look into the electrodes give be analyzed by being in a solution containing metal ions. This experiment tests the effects of contrastive length electrodes in voltaic cells. A voltmeter will be used to measure the voltage produced and determine if the length of the electrode has all(prenominal) last(predicate) bearing on the heart of volts created. Problem: How do paired length electrodes affect the voltage in voltaic cells? proceed: If the length of the electrode is long, hence the voltage will be low. Variables: self-employed person: Length of Electrodes Dependent: Voltage of Cell Control: com pactness and amount of solutions in well (.1M crap sulfate and coat sulphate), akin(predicate) sodium chloride bridges (length & concentration), very(prenominal) 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 all trial.

The salt bridges should be cut to the same surface and then all soaked in the saline solution. The same voltmeter should be used to measure all voltages a nd the experiment will be conducted at aroun! d the same time so that the temperature and pressure of the environment does not change. Materials: 100 mL .1M squealer 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
