Question
Chapter 9, Problem 3QP
Interpretation Introduction
Interpretation:
The incorrect features of the solubility graph of a compound which were measured in water at different temperature values are to be determined.
Concept Introduction:
Solubility indicates the property of a solid, gas or liquid compound which is known as a solute and dissolves in a solid, liquid or gaseous solvent.
The solubility of a substance depends upon the chemical and physical properties of the given solvent, solute, and temperature, pressure including the pH of the solution.

Solubility is the ability to dissolve certain substances(solutes) into a solvent.
You are a student in Mrs. Bateast's Chemistry class and you were given the assignment to compare
solubilities of salt in different solvents at different temperatures. You added salt at a consistent rate
and amount until you reached the point of full saturation. The amount added to each solvent at
saturation was recorded. The results of the experiment are shown in the tables:
Table 1:

Using CER and your knowledge from data listed above, if the temperature of ethanol solution
increased by an additional 10 degrees, what would happen? Construct a line graph is required as
well.

Sam drops a sugar cube into a jar with hot water and a sugar cube into a jar with cold water. Both jars have the same volume of water. He drops the sugar cubes at the same time and then observes how much of them dissolves in two minutes.
What will be the result of Sam’s experiment, and which statement should he use as his conclusion?
A
A greater amount of sugar dissolved in hot water because temperature is directly proportional to the
solubility rate of sugar in water.
B
Temperature does not affect the solubility rate of the sugar cube in water because sugar dissolves
equally in both cold and hot water.
C
A greater amount of sugar dissolved in hot water because temperature is inversely proportional to
the solubility rate of sugar in water.
D
A smaller amount of sugar dissolved in cold water because temperature is inversely proportional to
the solubility rate of sugar in water.
