Whether solution made with 6.5 g KNO 3 in 15.0 g of water at 45 ° C is saturated or unsaturated has to be determined. Also, mass percent of KNO 3 has to be determined. Concept Introduction: Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component that is present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is known as solvent. Types of solutions are as follows: 1. Saturated solution When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute becomes undissolved in such types of solutions. 2. Unsaturated solution When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute is dissolved in such solution. 3. Supersaturated solution. Such types of solutions consist of extra amount of solute than that can be actually dissolved in solvent.

Interpretation Introduction

Interpretation:

Whether solution made with 6.5 g KNO3 in 15.0 g of water at 45 °C is saturated or unsaturated has to be determined. Also, mass percent of KNO3 has to be determined.

Concept Introduction:

Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component that is present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is known as solvent.

Types of solutions are as follows:

1. Saturated solution

When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute becomes undissolved in such types of solutions.

2. Unsaturated solution

When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute is dissolved in such solution.

3. Supersaturated solution.

Such types of solutions consist of extra amount of solute than that can be actually dissolved in solvent.
