Question

Brine is
A.Aqueous solution of chlorides
B.Saturated solution of NaCl
C.Aqueous solution of HCl
D.Common name of bleaching powder

Answer 1

Brine (also known as saltwater) is a highly concentrated aqueous solution of common salt (otherwise sodium chloride). Natural brines are commercially important sources of common salt and other salts such as sulphates and potassium and magnesium chlorides. They occur underground, in seawater, or as salt lakes.
Brine can be formed through the dissolving of sediment deposits, such as those seen in salt domes. A salt dome is an earth science system in which incredibly dense layers of relatively plastic salt drained upward through the bedrock due to the good weight of this overlaid rock and silt.

Complete answer:
Option A: The ion is diamagnetic and colourless. Most chloride salts, such as silver chloride, lead (II) chloride, and mercury(I) chloride, are highly soluble in aqueous solution; however, some chloride salts, such as silver chloride, lead (II) chloride, and mercury(I) chloride, are only marginally soluble in water. The protic end of the water molecules binds chloride in aqueous solution.
So, option A is not correct.
Option B: Brine salt water is a very concentrated water solution, especially if it contains common salt, such as sodium chloride. Brine is formed when evaporite deposits, such as those found in salt domes, are dissolved in water.
So, option B is correct.
Option C: Hydrochloric acid, commonly known as muriatic acid, is a hydrogen chloride aqueous solution. The liquid is colourless and has a strong, pungent odour. It’s considered a strong acid.
So, option C is not correct.
Option D: Hypochlorite of calcium is an inorganic substance. It is the major active ingredient in commercial bleaching powder, chlorine powder, or chlorinated lime products that are used for water treatment and bleaching.
So, option D is not correct.

So, option B is correct.

Additional information:
The electrolysis of brine is a large-scale procedure for producing chlorine from salt on a massive scale. It's critical to keep the chlorine and sodium hydroxide created in the process separate since they react when they come into touch.
This technique produces hydrogen gas, chlorine gas, and sodium hydroxide solution on an industrial scale utilising sea water.

Note:
Brine is formed naturally on the crust's surface, on the Earth's surface (in salt lakes), and in brine pools on the ocean's bottom. The evaporation of ground saline water at high ambient temperatures usually results in the formation of a high concentration brine lake. At high ambient temperatures, brine can be utilised to boil saline water.
