Solubility-A physical property

Solubility is the measure at which an object dissolves into another. Solubility involves solids liquids and gases.

For example, when you stir in salt or sugar into water it has high solubility. When you stir some oil into water it has low solubility. If you add it in some sand, the sand is insoluble. Whenever you have a solution and stir something in or dissolve something the solute is what is being dissolved.

In this example, the sugar is the solute and the solvent is what is being dissolved into, which in this case would be the water. There are several things that impact the rate of solubility.

First, the temperature can impact the rate of solubility. With liquids and solids as the temperature increases the rate of solubility increases. However, with gas it is the opposite, as the temperature increases the solubility decreases.

The amount of pressure has little impact on liquid but does impact gas solubility. As pressure increases with gas, the solubility also increases.

Agitation is another activity that increases the rate of solubility. When you stir your glass of tea it increases the solubility because of increased agitation.

Finally, you can also increase the surface area and that also increases solubility. When you crush something into small pieces it will dissolve more rapidly.

Solubility the rate at which something dissolves into another object.
