ELECTROLSIS
Some solid materials or substance such as metals allow electric current to pass through them. Molten salts and some solution also conduct electricity.
- Conductor is the substance which allow electric current to pass through it.
Eg. Steel and metals
- Non Conductor (Insulator) is the substance which do not allow electric current to pass through. Eg. Wood, paper or rubber.
- Semiconductor or poor conductor is the substance which allow partially electric current have free electrons or mobile electrons. As movement of these free changed particles make it possible for material to conduct electricity.
ELECTROLYTE AND NON ELECTROLYTES.
Is the substance which desociate or decompose into free ions when they are in solution or molten state, thus allowing electric current to pass through.
Electrolyte always exist as solution of acid or base or salts.
Eg. NaCl > Na + + Cl-
NON-ELECTROLYTE
Is the solution or molten state which do not conduct electricity.
Non-electrolyte do not dissociates into ions in solution or molten state, there fore they don't have free electrons to conduct electricity.
There are other molten materials such as copper ( Cu ) conduct current but they are not electrolyte.
This is because conduction of electricity in metal is done by electrons and not ions, and also the metal do not decompose when electricity pass through them.
