Question

What name is given to the common salt which is mined from underground deposits? How was this salt formed?

Answer 1

Hint :In order to answer this question, first we will mention the common salt name which is mined from underground deposits. And then we will explain the whole process of the formation of the required common salt.

Complete Step By Step Answer:
Rock salt is a common salt that is produced in huge crystals from underground sources and is chemically known as Sodium Chloride $ (NaCl) $ .
Sodium chloride is a compound formed from the ionic bonding of sodium and chloride. When sodium atoms interact with chlorine atoms, sodium chloride is generated. Chlorine will get an electron (a negatively charged particle) from sodium. As a result, sodium becomes slightly positive, $ N{a^ + } $ and chlorine becomes slightly negative, $ C{l^ - } $ . Sodium contributes an electron to chlorine, and chlorine gains an electron and is oxidised, resulting in sodium being reduced in this process.
Sodium has an atomic number of 11, its electrical configuration is \[2,8,1\] . In the outermost shell of the sodium atom, there is only one electron. As a result, the sodium atom donates one electron, forming the sodium ion \[N{a^ + }\] .
 $ Na - {e^ - } \to N{a^ + } $
Chlorine has an atomic number of 17, its electronic configuration is \[2,8,7\] . The outermost shell of a chlorine atom has seven electrons, and it requires one additional electron to create the stable, eight-electron inert gas state. As a result, a chlorine atom loses one electron, resulting in the negatively charged chloride ion $ C{l^ - } $ .
 $ Cl + {e^ - } \to C{l^ - } $
When sodium reacts with chlorine, it transfers one of its outermost electrons to the chlorine atom, losing one electron and generating sodium ion ( $ N{a^ + } $ ), while the chlorine atom gains one electron and produces chloride ion ( $ C{l^ - } $ ).
Positive charges are found in sodium ions, while negative charges are found in chloride ions. The electrostatic force of attraction holds sodium and chloride ions together to create sodium chloride $ N{a^ + }C{l^ - } $ or $ NaC{l^ - } $ due to their opposing charges.

Note :
 Solution mines are known as brine wells when they are near chemical companies, and the salt is used in chemical manufacture. After the salt is taken from a mine, the empty space is frequently used to store other materials such as natural gas or industrial waste. Salt is extracted from saltwater or salt lakes via solar evaporation.
