Identify the acid and base from which sodium chloride is obtained.which type of Salt is it ?why it is called Rock Salt? How is it obtained
Answers
Answer:
Sodium chloride is a neutral salt as its constituent acid and base both are strong. It is called rock salt when it is found in form of crystals and it is then mined like coal. Rock salt is formed by the crystallisation of sodium chloride (common salt). It is darker in colour due to impurities.
Answers with respect to salt are given below -
Sodium chloride is obtained from acid and base by a reaction known as neutralisation reaction.
Acid and base react to form sodium chloride are hydrochloric acids and sodium hydroxide respectively.
Industrial production of sodium chloride is from seawater or salt lakes. The water is evaporated to remain salt particles which are purified to remove impurities.
Salt mining is also a source of sodium chloride.
Sodium chloride is sea salt. It is also called rock salt because it is obtained from halite which is a mineral form of sodium chloride.
Halite is found where minerals containing rocks of masses are formed.
