If 100 grams of potassium nitrate is dissolved in 100 cm3 of water at 60oc, a(n) solution is formed.
a. saturated
b. unsaturated
c. oversaturated
d. supersaturated

- b) unsaturated

explanations:- From solubility curve, 108 g of potassium nitrate are soluble per 100 g of water (100 cubic centimeter).

So, if exactly 108 g of potassium nitrate are dissolved in 100 of water then solution will be saturated. If less than 108 g of potassium nitrate are dissolved then solution will be unsaturated and if greater than 108 g of potassium nitrate are dissolved then solution will be super saturated.

Since, only 100 g of potassium nitrate are dissolved per 100 of water, the solution is unsaturated.
