Question 2.6.1
The solvents, isooctane and carbon tetrachloride, are organic liquids that are insoluble in water, and this causes two distinct liquid phases, an organic phase
and a water phase, to form when these solvents are mixed with water.

a. In the isooctane/water mixture, the water phase is on the bottom, and the organic phase is on the top. What can be deduced about the relative density of
isooctane and water?
isooctane is less dense than water.
isooctane is more dense than water.
isooctane and water have the same density.
Nothing can be deduced about the relative density of isooctane and water.

b. In the carbon tetrachloride/water mixture, the water phase is on the top, and the organic phase is on the bottom. What can be deduced about the relative
density of carbon tetrachloride and water?
carbon tetrachloride is less dense than water.
carbon tetrachloride is more dense than water.
carbon tetrachloride and water have the same density.
Nothing can be deduced about the relative density of carbon tetrachloride and water.
If you are unsure how to complete this section of the question, assistance is available in Hint c.

c. Using the information in the previous two questions, what can be deduced about the relative density of isooctane and carbon tetrachloride?
isooctane is less dense than carbon tetrachloride.
isooctane is more dense than carbon tetrachloride.
isooctane and carbon tetrachloride have the same density.
Nothing can be deduced about the relative density of isooctane and carbon tetrachloride.
