1. Write two main differences between conducting of electricity through metals
and solution of electrolyte.(Do not write more than two differences)
Answers
Explanation:
A 'difference between' Site. Simple point wise difference between biology, physics and chemistry.
Metallic Conduction vs Electrolytic Conduction
The substances which allow electricity to pass through them are called conductors.
Example of conductors: Metals, bases, salts, Solution of acids.
The conductors are of two types: Metallic conductors and Electrolytic conductors) Metallic conductors or Electronic conductors are substances which allow the passage of electricity through them without undergoing any chemical change. In these, electricity is carried exclusively by the transport of electrons. Hence these are also called electronic conductors.
Example of Metallic conductors: Alloys, Graphite, Metals
b) Electrolytic Conductors or Ionic conductors are substances which allow the passage of electricity through them in their molten states or more commonly, in their aqueous solutions and undergo chemical decomposition. In these, electricity is carried by the movement of positive and negative ions. Hence these are also called ionic conductors.
Example of Electrolytic conductors: Acids, bases and salts.
Metallic Conduction vs Electrolytic Conduction
Metallic Conduction
Electrolytic Conduction
The flow of electric current is due to the flow of electrons.
The flow of electric current is due to the flow of positive and negative ions.
There is no transport of matter during the flow of electricity.
There is actual transport of matter (in the form of ions)during the flow of electricity.
Metallic conduction decreases with increase in temperature.
Electrolytic conduction increases with increase in temperature.
The flow of electricity occurs without any chemical decomposition.
The flow of electricity take place with chemical decomposition of the electrolyte.
