Define the following :a) Cell potential b) Cell electromotive force c) Galvanic cell d) Electrolytic cell e) Standard electrode potential
Answers
Answer:
Explanation:
a)The batteries in your remote and the engine in your car are only a couple of examples of how chemical reactions create power through the flow of electrons. The cell potential is the way in which we can measure how much voltage exists between the two half cells of a battery. We will explain how this is done and what components allow us to find the voltage that exists in an electrochemical cell.
b)The voltage or electric potential difference across the terminals of a cell when no current is drawn from it. The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell.
c)A galvanic cell or voltaic cell, named after Luigi Galvani or Alessandro Volta, respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.
d)An electrolytic cell uses electrical energy to drive a non-spontaneous redox reaction. An electrolytic cell is a kind of electrochemical cell. It is often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means to break up.
e)In electrochemistry, standard electrode potential is defined as the measures the individual potential of reversible electrode at standard state with ions at an effective concentration of 1mol dm⁻³ at the pressure of 1 atm.
