Mixtures
Define Homogeneous Mixture
What is a mixture you cannot see the different parts?
State the relationship between pressure and the solubility of gases
What is an increase in pressure causes more of the gas to dissolve
Define Solute
What is present in the smallest amount/what get dissolves?
Determine the range of the pH scale, noting weak acids, strong acids, neutral, weak bases and strong bases
What is closer to 0=strong acid, closer to below 7=weak acid, 7= neutral, closer to above 7=weak base and closer to 14= strong base
a plotted point that is on the solubility curve line
What is a saturated solution?
Define heterogeneous mixtures.
What is a mixture in which you can see the different parts?

Define colloid
What is a mixture in which some particles are not dissolved?
Determine the relationship between warmer temperatures and the solubility of gases
What is there are less gas particles to dissolve in warmer temperatures?
Define dilute concentration
What is a weak solution with little solute?

These have a bitter taste
What are bases
Define Suspension
What is a mixture in which you can easily see undissolved particles and they can be separated
Define solubility
What is the amount of a substance that can be dissolved at a given temperature
Differentiate between a solution, colloid and suspension
What is a solution has small particles too small to be seen, colloids have some particles that can be seen and suspensions have large particles that can be filtered out?
Compare the hydrogen and hydroxide ions of bases
