Question

The formula of sodium chloride is $ NaCl $ :
A. True
B. False

Answer 1

Hint: In order to answer this question, to know whether the given statement is true or false, we should go through the mechanism and the chemical structure of sodium chloride. And we will also discuss more about the production and occurrence of the sodium chloride.

Complete answer:
Yes, the given statement is true because the chemical formula of sodium chloride is $ NaCl $ .
Sodium chloride is one of the most well-known and widely used chemicals, also known as table salt.
The chemical formula of sodium chloride is $ NaCl $ and its molar mass is $ 58.44{\text{ }}g/mol $ . It is an ionic compound consisting of a sodium cation $ (N{a^ + }) $ and a chloride anion $ (C{l^ - }) $ . Solid $ NaCl $ has a crystalline structure, in which each $ N{a^ + } $ ion is surrounded by six chloride ions in an octahedral geometry.
Sodium chloride is present in the sea and ocean waters, giving them their saltiness. About $ 1 - 5\% $ of seawater is made of sodium chloride. It is also found as the mineral halite or rock salt.
Salt is produced on large scales by evaporation of sea water or the salt water (brine) from salt lakes and brine wells. As seawater contains several other salts (of calcium, magnesium and other elements), the evaporation process is carried out carefully so that the different salts precipitate out at different times based on their solubility. Another major production method is by mining the rock salt reserves.
Hence, the correct option is (A).

Note:
Solid $ NaCl $ has a crystalline structure, in which each $ N{a^ + } $ ion is surrounded by six chloride ions in an octahedral geometry. Occurrence: Sodium chloride is present in the sea and ocean waters, giving them their saltiness.
