IONIC THEORY

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.
