Question

Saturated solution of sodium chloride called as?
A) Crystal
B) Brine
C) Lime
D) Soda ash

Answer 1

An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved. A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved.

Complete Answer: B
At $20^\circ C$, the maximum amount of $NaCl$ that will dissolve in 100 g of water is 36.0 g. If any more $NaCl$ is added past that point, it will not dissolve because the solution is saturated. Recrystallization is the process of dissolved solute returning to the solid state. At some point the rate at which the solid salt is dissolving becomes equal to the rate at which the dissolved solute is recrystallizing. When that point is reached, the total amount of dissolved salt remains unchanged. Solution equilibrium is the physical state described by the opposing processes of dissolution and recrystallization occurring at the same rate. The solution equilibrium for the dissolving of sodium chloride can be represented by one of two equations.
$NaCl(s)\underset {} \leftrightarrows NaCl(aq)$
While this shows the change of state back and forth between solid and aqueous solutions, the preferred equation also shows the dissociation that occurs as ionic solid dissolves.
$NaCl\underset {} \leftrightarrows N{a^ + } + C{l^ - }$

Correct option is B as brine is a saturated solution of sodium chloride.

Note:
Sodium chloride is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions. Sodium chloride is used to treat or prevent sodium loss caused by dehydration, excessive sweating, or other causes.
