A KNO3 solution containing 45 g of KNO3 per 100.0 g of water is cooled from 40 ∘C to 0 ∘C. What will happen during cooling? Match the words in the left column to the appropriate blanks in the sentences on the right.

(A) 58

(B) 14

(C) 85

(D) 55

(E) 35

(F) 63

(G) 41

(H) 10

At 40 ∘C the solution has g of KNO3 per 100 g of water and it can contain up to g of KNO3 per 100 g of water. At 0 ∘C the solubility is ~ gKNO3per 100 g of water, so gKNO3 per 100 g of water will precipitate

Hello my friend! The amount of 31g of KNO3 will precipitate!

Explanation:

At 40 ∘C the solution has 45 g of KNO3 per 100 g of water and it can contain up to 63 g of KNO3 per 100 g of water. At 0 ∘C the solubility is ~ 14 gKNO3per 100 g of water, so 31 gKNO3 per 100 g of water will precipitate
