DENSITY
amount of matter in an object
If I asked you to make a saturated solution of potassium chloride in 100 grams of water, what other piece of information would you need before you could start?
temperature and grams of solute
what is concentration?
What is the amount of substance in a defined space
Identify the following: NaOH
What is a Base
the amount of space something takes up
What is Volume
if the student crushes up the solute how does that effect the solubility.
What is it will dissolve faster.

What is 80 grams of KNO3
Reacts with base to form salt and water
What is an acid
Density= Mass/Volume

Blue Litmus paper turns Red in the presence of an Acid
Density does NOT depend on what?
What is: amount
maximum amount that can be dissolved in a specific amount solvent
Solubility
