SC1 Physics Mr. Poore Group 1 Kelly Wainwright 10DB Electrolysis of aquatic salt solution I am going to investigate what elements are made at the electrodes and if there is a pattern. The input variable is: * The solution I use The out come variables are: * The element at cathode * The element at anode The controlled variables are: * The voltage of the power pack * The concentration of the solution Electrolysis is the process by which an electric current is passed through a substance which will result in a chemical change. The chemical change is one in which the substance loses or gains electrons (oxidation or reduction). The process is carried out in an electrolytic cell , an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing a compound. The substance to be transformed may form the electrode, may make up the solution, or may be dissolved in the solution. The electric current enters through...
