Question

define the following term electrolyte electrolysis electrodes voltameter voltmeter electrore fining

Answer 1

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water

electrolysis
electrolysis is a technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction. 
electrodes

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit
voltmeter
A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. 
electrore fining
Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. 

Answer 2

Electrolyte- A substance which gives ions when melted or dissolved in water it is called an electrolyte .

Electrolysis- Decomposition of an electrolyte bypassing electricity throw it is called electrolysis .

Electrodes- A metallic wire or rod through which electric current either enter or leaves and electrolytic solution is called an electrode these are two types cathode and anode.

Voltameter- A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit.

Voltmeter- A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit.

Electrore Fining- Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell.An electric current is passed between a sample of the impure metal and a cathode when both are immersed in a solution containing cations of the metal.
