Solutions

1. Solute – What is dissolved (put in)2. Solvent – What does the dissolving (liquid)3. Solution – Combination of solute and

solvent4. Solubility – measure of the amount of

solute that will dissolve in a given amount of solvent

Solution Types

5. Saturated– Solution containing the max amount of solute able to be dissolved under certain conditions

6. Unsatruated– solution having the capability to dissolve more solute under certain conditions

7. Supersaturated – to increase the concentration of a solution beyond saturation

Temperature and Solubility

The temperature of the solution affects how much of the solute is dissolved by the solvent.

Increasing the temperature does not always increase the solubility but usually.

Solubility curves are used to show how the solubility of a substance changes with temperature.

To read the graph, lines equal substances. The amount that dissolves is on the y-axis.The temperature is on the x-axis.

How much KNO3 dissolves in 100g H2O at 50oC?

1. Find the substance line (red)

2. Find the temperature and follow up to the red line. (green)

3. Read across to the y-axis and this is the answer. (blue)

4. Since it is above the ½-way between 80 and 90, it is 87.

Lines that increase are liquids

Lines that decrease are GAS

A point on the line is a saturated solution.

Above the line is supersaturated.

Below the line is unsaturated.
