[edit] Electrolytes And Non-electrolyte
[edit] Conductor
A conductor is a substance which conducts electricity but is not chemically changed during the conduction .
[edit] Insulators
A non-conductor is a substance which does not allow the passage of electricity. Sometimes these non-conductors are used to protect something from electricity. They are then called insulators .
[edit] Electrolytes
Electrolytes are compounds which when molten or dissolved in water conduct electric current and are decomposed in the process .
[edit] Non-electrolyte
A non-electrolyte is a liquid which does not allow the passage of electricity.
[edit] Examples of non-electrolytes, weak electrolytes and strong electrolytes
- Examples of electrolytes are acids, alkalis and salts dissolved in water or molten salts .
- All these are ionic substances.
- Solid ionic substances do not conduct electricity, as their ions are held together in fixed positions by strong forces .
- In order for the ions to move, the solid must be dissolved in water or made molten, thereby destroying the ionic lattice .
