IONIC THEORY
- Ionic theory say that ionic compounds desociate to form ions.Eg. MX > M+ + X-
Where;
M represent metal (eg Na, Mg and so on)
X-represent non mete (eg Cl, NO3-, and so on
- After desocition of ionic compounds ions are free to move and support passage of electricity through solution
- The power supply connected are connected and electrodes are charged
- cation move to cathode and anions move to pistively charged particle
Electrolysis
Electrolysis is the process in which an electric current is passed through an electrolyte causing a chemical reaction to occur.
Action happen at anode;
At anode oxidation take place
X- > X + e
Action happen at cathode;
At cathode oxidation take place
M+ + e > M
- Electrode;
Is the component of the cell which make contact with the electrolyte.
- Cathode is Electrode attached to negative terminal
Or
Cathode is an Electrode through electrons enter the electrolyte
- Anode is an Electrode attached to positive terminal
Or
Anode is an Electrode through which electrons enter the electrolyte.
