Solubility & Solubility Curves

What is a SOLUTION: a homogenous mixture in which the substances are evenly mixed.

Solute: the substance being dissolved
Solvent: the substance doing the dissolving

Multiple Choice

When making kool aid, the flavor mix is the

solute

solvent

Multiple Choice

When making kool aid the water is the

solute

solvent

It is important to remember that solubility of a solid is related to temperature.

Higher temperature = increase in solubility
Lower temperature = decrease in solubility

Temperature and solubility curves

As the temperature of a solution changes, the maximum amount of solute that can be dissolved will also change.

Solubility curves are used as a reference tool. They tell you how much solute will dissolve in a solvent at a certain temperature. They also allow you to see how solubility changes with temperature.
