Question

20 g of sodium chloride is dissolved in 100 ml of of water. How will you test whether the given solution is saturated or unsaturated or supersaturated at the given temperature ?

Answer 1

add more NaCl in it
if it dissolve then solution is unsaturated
if it does not dissolve then solution is saturated

Answer 2

Test to determine the saturation of the sodium chloride solution.

Explanation:

• Take 20g of sodium chloride in a beaker and add 100ml of water to it and mix it thoroughly.
• When the solution doesn't accepts more than 20g of sodium chloride (Solute), it is considered a saturated solution.
• On the other hand, if the solution accepts more than 20g of sodium chloride, it is considered an unsaturated solution.
• In the given case formation of crystals indicate that the solution is saturated whereas non-formation of crystals indicates that the solution is unsaturated.
