A current produced in an electrolytic solution can deposit a film of metal on objects with microscopic accuracy. Electrochemical methods are used in chemical analysis and to produce electric current from a cell or battery. The science that deals with these processes is called electrochemistry. Its principal application is to break down a complex compound into simpler ones or to separate a compound into its elements. This is done by electrolysis.
Electrochemical terms imply the use of current.
The substance to be changed is called the electrolyte. The pole that supposedly led this flow into a solution is called an anode. It moves through the solution to the cathode. Water has its solvent properties because it is polar. These charged ends react with charges on other polar substances to dissolve them.
