Brief explain

When three tablespoons of salt are mixed into a glass of water and stirred, about a teaspoon of water-saturated salt remains on the bottom. If a small % of salt is slowly added to the glass while stirring the solution, the change in concentration of the salt in the solution is given by curve:

Solution

As we know that the solubility of salt in 1 litre of water at room temprature is 357 gram.

1 glass of water which is equal to approximatly = 200 mililitre,

so solubility in 200 ml will be approx. = 357/5 = 71.4mg = 72mg

according to standard 1 tablespoon = 15gm

so 3 tablespoon will be = 45 gm

so concentration will be incresed till 72 gm so curve a will be correct explaination.
