Document Summary
****we completed more practice problems for last class"s. Concepts and then moved on with the following*** Concentration cell: two half cells with the same components in each, but in different concentrations of ions. In this case, the same ion could be both oxidized and reduced within the total reaction. Batteries: self containing voltaic cells that are in series arrangement. So individual voltages are added for the total. Primary battery : cant be recharged, in equilibrium the cell battery is referred to as dead . Secondary battery : rechargeable, electrical energy is supplied to reverse the reaction to form more reactant for the forward reaction example is the lithium ion battery. Dry cell : has no fluid components, usually a jelly consistency. Corrosion: deterioration of a metal through an electrochemical process. 1) galvanization: covering the metal surface to preserve the metal in a normally corrosive environment.
