Question

Substance A dissolves in water. What can be said about substance A?
O It is unsaturated.
It is nonpolar.
It is saturated.
It is polar.

Answer 1

Answer:

It is polar.

Explanation:

Water is a polar solvent and it can only dissolve another solute or substance.

As a general rule of solubility "likes dissolves likes".

This implies that when a polar solvent is used, it will dissolve a polar solute.

Also, a non-polar solute will only dissolve in a non-polar solvent.

• Water is an example of polar solute.
• Other solutes such as salt can dissolve in water because they are polar in nature.
• A non-polar solvent is oil.
