Understanding Solubility and Saturation States

This video tutorial explains how to use solubility graphs to determine the saturation states of solutions. It covers reading solubility graphs, understanding saturation states (unsaturated, saturated, supersaturated), and provides examples using potassium iodide and potassium nitrate. The tutorial also demonstrates how to graphically analyze solutions to determine their saturation state at various temperatures.

What is the term used for a solution that contains less solute than the maximum amount it can dissolve?

• Concentrated

• Supersaturated

• Unsaturated

• Saturated

At 30 degrees Celsius, if a solution contains 10 grams of potassium nitrate, what is its saturation state?

• Concentrated

• Supersaturated

• Unsaturated

• Saturated

If a solution at 30 degrees Celsius contains 70 grams of potassium nitrate, what is its saturation state?

• Diluted

What is the saturation state of a solution at 90 degrees Celsius with 130 grams of potassium nitrate?

• Saturated

• Unsaturated

In a crowded solubility graph, what is the saturation state of a solution at 30 degrees Celsius with 50 grams of sodium chloride?

• Diluted

• Saturated

• Unsaturated

• Supersaturated

What is the saturation state of a solution at 75 degrees Celsius with 150 grams of potassium nitrate?

Which of the following best describes a supersaturated solution?

• It contains less solute than it can dissolve.

• It is a diluted solution.

• It contains the maximum amount of solute it can dissolve.

• It contains more solute than it can normally dissolve.
