Question

If 180 grams of potassium iodide is dissolved in 100 cm3 of water at 30oC, a(n) _______________ solution is formed. A) saturated B) unsaturated C) oversaturated D) supersaturated Eliminate

Answer 1

The answer is A) saturated

Answer 2

Answer:

A) saturated

Explanation:

In an unsaturated solution, the solute is lower than the solvent in the chemical solution. When this occur, there is higher rate of dissolution of the solute in the solvent

A saturated solution is said to be a chemical solution in which the concentration of solute that is dissolving in the solvent is of equal proportion and at maximum  amount,

In a supersatured solution, there exists more solute than the solvent in the chemical solution. When this occur, there is higher rate of crystallization of the solute in the solvent

A solubility curve helps to show a diagrammatic graphical based representation of the amount of solute that is required to dissolve in a given amount of solvent at different temperatures.

Thus, potassium iodide is indeed soluble in water. At 20°C, it is said that the solubility of potassium iodide is 140 grams per 100 cm³ of water. This is similar to the 180 grams of potassium iodide which dissolves in 100 cm³ of water at 30°C because increase in temperature also increases the solubility of a solute in a solvent.
