Question

Which property of graphite is utilised in making electrodes?

Answer 1

Hint: Free Electron causes the conductivity of electricity.Carbon Atom contains free electrons in its Valence Shell. Conductivity is a physical property.

Complete step by step solution:
As we know that, Graphite consists of carbon atoms. Each carbon atom has a free electron in its valence shell, and the free electrons are responsible for the conductivity of electricity.
So, Graphite is a good conductor of heat and electricity.
Graphite is also known as “plumbago” or “black lead”, consists of carbon.Graphite is dark gray to black, opaque, and very soft in nature as compared to diamond. Mainly it is mined in India, China, Brazil, North Korea and Canada on a very large scale.
Graphite is shaped by the transformation of dregs containing carbonaceous material, by the response of carbon mixes with aqueous arrangements or magmatic liquids, or conceivably by the crystallization of magmatic carbon.
 It happens as disengaged scales, huge masses, or veins in more seasoned glasslike rocks, gneiss, schist, quartzite, and marble and furthermore in stones, pegmatites, and carbonaceous mud records.

Additional information:
Graphite was first blended inadvertently by Edward G. Acheson while he was performing high-temperature probes carborundum. Acheson was granted a patent for graphite make in 1896, and business creation began in 1897.

Note: Graphite or “graphite paste” is used for electrodes because:
a.) it is Conductive in nature.
b.) it is inexpensive.
c.) it can continuously expose a “fresh” surface.
