What is the result of boiling the impure product with too much solvent and then cooling on ice?

The result of boiling the impure product with too much solvent and then cooling it on ice is the crystallization of the pure product, that is, the removal of the impurities present in it. This process in chemistry is called recrystallization.

Explanation:

The recristallization is a purification technique to separate a high value crystalline product from unwanted impurities dissolved in the mother liquor. Strictly speaking, recrystallization is a process in which an initially solidified crystalline material re-dissolves and crystallizes to produce final product crystals of the desired size, shape, purity and yield.

The first step of recrystallization is a solvent selection procedure based on potential risk, environmental impact, purchase and disposal cost.

Depending on its molecular structure, a solute can be classified as soluble, partially soluble or insoluble in these solvents or solvent mixture. To understand this thermodynamic relationship, it is necessary to evaluate the temperature-dependent solubility behavior of the solute in a wide range of different solvents. The solubility can be high or low at room temperature, a function of the temperature that increases strongly, or almost independent of the temperature at all.

is there multiple choice answers?

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
