Solutions and Solubility

​Solubility

When determining the solubility of a subtance you must have a solute and a solvent.​

​

​Solubility is the ability to dissolve.

​

​SOLUTE- is a substance that can be placed into a solvent.

​

example:

• sand

• salt

• flour

• powder​

• sugar​

​

​SOLVENT- is a substance used to dissolve things such a solvent.

​

example:

• water​

​How to determine solubility?

​Solubility

Solubility is determined based on a substance ability to dissolve. A substance such as sand is considered to be insoluble (-unable to dissolve) because when sand and water is mixed, the solute sand, settles at the bottom. Sugar on the other hand, when mixed in water is considered to be soluble (-capable of being dissolved) because when sugar is mixed in water it dissolves evenly amongst the solvent.​

Multiple Choice

Which substance is insoluble?

• salt

• sugar

• sand

• powder

Multiple Choice

A substance incapable of being dissolved is

• solute

• solvent

• soluble

• insoluble

Multiple Choice

which statement best describes a solvent from a solute.

• a solute is the substance that is place into the solvent.

• an example of a solvent is salt.

• an example of a solvent is sugar.

• a solvent is a solid placed into a solute.

Multiple Choice

Which of the following can increase the dissolving rate of a substance the most?

• mixing

• freezing

• heating it up

• adding more substance.

​WATER IS A UNIVERSAL SOLVENT

​

MEANING IT CAN DISSOLVE MANY DIFFERENT MOLECULES WHICH MAKES IT A GREAT SOLVENT.
