Chapter 7: Acids, Bases, & Solutions
a well-mixed mixture that contains a solvent and at least one solute.
the part of a solution present in the largest amount.
is a mixture containing small, undissolved particles that do not settle out.
what gets dissolved by the solvent
is a mixture in which particles can be seen and easily separated by settling or filtration.
a mixture that has only a little solute dissolved in a certain amount of solvent.
a solution that has a lot of solute dissolved in the same amount of solvent.
is a measure of how much solute can dissolve in a solvent at a given temperature.
if you can continue to add more solute to the solution
has more dissolved solute than is predicted by its solubility at the given temperature.

compound that changes color when in contact with an acid or a base
