Question

part a. Based on the model Solute and Solvent, for the following common solutions identify the solvents in the following mixtures:

1. soda

2. vinegar

3. vodka

4. sea water

5. rubbing alchohol (70% isopropanol)

a. ethanol

b.oxygen

c. water

d. isopropanol

e. carbon dioxide

f. acetic acid

part b. Based on the model Solute and Solvent, for the following common solutions identify the solutes in the following mixtures:

1. soda

2. vinegar

3. vodka

4. sea water

5. rubbing alchohol (70% isopropanol)

A.	Methanol
B.	Oxygen
C.	Acetic acid
D.	Carbon Dioxide
E.	Water
F.	Sodium chloride
G.	Carbonic acid
H.	Ethanol

part c. label which is saturated, unsaturated, supersaturated

1. A solution where the maximum solute has not been dissolved into the solvent and more solute can be added

2. A solution in which the addition of ANYMORE solute will precipate out as a solid.

3. A solution in which more solute is dissolved than the solvent can dissolve under normal conditions.

4. It has occurred in the process of making Rock Candy

5. Southern Style Sweetened Tea

6. Unsweetened Black Tea

Answer 1

A)

solvent --> species present in mayor amount

1. soda --> water

2. vinegar --> water

3. vodka --> water

4. sea water --> water

5. rubbing alchohol (70% isopropanol) --> isorpopanol

B)

find solutes

1. soda --> CO2 and H2CO3 mostly

2. vinegar --> acetic acid

3. vodka --> ethanol

4. sea water --> oxygen, CO2, sodium chloride, H2CO3 (carbonic acid)

5. rubbing alchohol (70% isopropanol) --> water

part c. label which is saturated, unsaturated, supersaturated

1. A solution where the maximum solute has not been dissolved into the solvent and more solute can be added --> unsaturated, since more solute can be added

2. A solution in which the addition of ANYMORE solute will precipate out as a solid. --> saturated, since no more can be added

3. A solution in which more solute is dissolved than the solvent can dissolve under normal conditions. --> supersaturated, sinc eit is already in excess

4. It has occurred in the process of making Rock Candy --> supersaturation

5. Southern Style Sweetened Tea ---> unsaturated

6. Unsweetened Black Tea --> unsaturated
