Answer the following questions using information from your knowledge of solutions.
1) What phrase did you know that explains if two substances will dissolve in each other?
2) In a solution, is the solute or solvent the substance that there are LESS particles of?
3) An unsaturated solution is a solution where there are still "empty spaces" between the base units of the solvent particles? True or False.
4) Looking at your Solubility Tables, if you add enough solute into 100g of water so that you are "over" the saturation point (line on the graph) would indicated that you had which one of the following solutions, a) unsaturated solution, b) saturated solution, and c) saturated solution with "undissolved" solute.
5) If you increase the temperature of a solution, how does the solubility changes for:
a) a solid solute? Increase, decrease, or stay the same
b) a gas solute? Increase, decrease, or stay the same
c) Explain what causes either of these?
6) Give two ways you can increase the rate of dissolving:
a)
b)
7) What is the phrase you need to know to explain how solute dissolves in a solvent to create a solution?
8) Is a the freezing point of a solution GREATER THAN, LESS THAN OR SAME than the freezing point of the solvent?
9) Is a the boiling point of a solution GREATER THAN, LESS THAN OR SAME than the boiling point of the solvent?
10) What phrase do you need to know to explain the Colligative Properties (see Question 8 & Question 9 above).
