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 assert 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 study the electrodes bequeath be analyzed by being in a solution containing metal ions. This experiment tests the effects of mismated length electrodes in voltaic cells. A voltmeter will be used to measure the voltage produced and determine if the length of the electrode has either last(predicate) bearing on the heart of volts created. Problem: How do pivotal length electrodes affect the voltage in voltaic cells? accident: If the length of the electrode is long, hence the voltage will be low. Variables: free lance: Length of Electrodes Dependent: Voltage of Cell Control: slow-wittedness and amount of sol utions in well (.1M copper sulfate and surface sulphate), akin(predicate) sodium chloride bridges (length & concentration), like 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 either trial.

The salt bridges should be cut to the same sizing and then all soaked in the saline solution. The same voltmeter should be used to measure all voltages and the experiment will be conduct ed at around the same time so that the tempe! rature and pressure of the environment does not change. Materials: 100 mL .1M horseshit Sulfate (CuSO4? 5 H2O ) 100 mL .1M zinc Sulfate (ZnSO4?
