(b) Who would be able to prepare a saturated solution.
Saturation solution: A solution in which no more soluble substance can be dissolved at room temperature or a given temperature.
Saturation is the point at which a solution of a substance can dissolve no more of that substance and an additional amount of heat substance will appear as a precipitate.
Case I Sarika
Sarika was given a teaspoonful of salt and half a glass of water. A sufficient amount of salt will be dissolved in water. As a result salt solution will form.
Case II Mohan
Mohan was given twenty teaspoonfuls of salt and half a glass of water. After the addition of salt, a certain point is reached where no more salt can be dissolved in water, it becomes a saturated solution. Some salt will remain undissolved and settled at the bottom of the glass.
Final answer: In Mohan's case saturated solution is formed.
