Both Sarika and Mohan were asked to make salt solution. Sarika was given a teaspoonful of salt and half a glass of water. Whereas Mohan was given twenty teaspoon full of salt and half a glass of water.
Sarika and Mohan will mix salt with water within a certain amount to make salt solution. Hence, Sarika will make a better salt solution.
Saturation is a point at which a substance cannot dissolve no more of a substance and additional amount of that substance will appear as a precipitate. Mohan’s solution would be saturated because in his case, some salt would remain undissolved and settled at the bottom of the glass.
