Test 10 ~ Objective 2

Objective 2:


1. Concentration is the measure of how much of another substance is in a different substance. To measure, you need to know the ratio of the solvent to the solute.


2. Solubility can be useful in finding the substances because it is a characteristic of common matter.  The common characteristic of solubility can be used to figure out how much of a certain substance can be dissolved in the solvent.  So, if you know the solubility, then you know how much of a solute can be added to the solvent until it is at its maximum concentration, which I talked about in the first question.  


3. The three factors that affect solubility are temperature, pressure, and polarity.


4. Heat is needed to break the bonds that holds the molecules together, and solubility depends on heat.


5. Solubility is helpful in seeing the substances because you can see how much of something is able to be dissolved in it.
