In this laboratory voltmeters where utilized to take reading of three different electrochemical reactions: Pb/Zn‚ Pb/Cu‚ and Zn/Cu. A salt bridge was placed between two reactions containing metal strips in separate aq solutions. The salt bridge was placed in order to balance the reaction. The voltage measurements for Pb/Zn‚ Pb/Cu‚ and Zn/Cu where .595 V‚ .479 V‚ and 1.072 V accordingly. The values obtained where then used to determine the voltage value for the reduction half. The resulting cell potential

Case study on Internal resistance of chemical cells Chemical cells “A chemical cell converts chemical energy into electrical energy. “Most batteries are combined by several chemical cells. “A chemical reaction occurs inside the battery and causes electric current to flow. There are two main types of batteries‚ which are rechargeable and non-rechargeable.” The application of chemical cells covers wide range in our life. “Batteries are manufactured in many shapes and sizes‚ from very small ones

OHM’S LAW AIM OF THE EXPERIMENT Confirmation of OHM’S LAW THEORY: It was George Simon Ohm (1787-1854) who established experimentally that the current in a metal wire is directly proportional to the potential difference V applied to its two ends‚ provided that the physical conditions such as temperature remain constant: I∞V Exactly how much current flows in a wire depends not only on the voltage‚ but also on the resistance the wire offers to the flow of electrons. Electrons are showed
