ncentration of fe and zn effect the voltage in an electrochemical cell BY DR. ROHAN NASSER OBIED

Background

Electrochemical cells are different since they do not undergo the normal reactions. However, it should be noted that the voltage amount that a cell produces is affected by several factors which affect the rates of the chemical reaction involved. These factors include concentration, temperature as well as surface area, (Selverston, Savinell, & Wainright, 2017). This experiment is going to investigate the effect that concentration has on the voltage.

This experiment is based on the science behind the Voltaic cell involving the harnessing redox reactions which generate electricity. By oxidizing the Iron (the solution mixture between Fe and Fe) and the lon to be transferred (it is transferred through a salt bridge which includes concentrated solution of an ionic salt such as KCI, to prevent a build-up of charges on both of the half cells) to the Copper sulphate (therefore it will be reduced) an exothermic reaction occurs. However, instead of the energy that is produced as a result being expressed as heat, it is converted to electrical energy. (Bagotsky, 2005). An example of a redox reaction (equation) between Zn and Cu as half cell
