Textbook Question
Chapter 10.9, Problem 10.20YT
Maybe you have been to a party or outdoor barbeque where they placed a variety of regular and diet sodas in a cooler or tubs with ice water. Are all the cans floating or at the bottom? Or, do some float and some sink? Think about what might be causing this difference, in terms of the compositions of the various types of sodas. Conduct some research to determine why this occurs.

Students have asked these similar questions
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.
Which of the following given statements is false?
1. The electrical conductivity of water is dependent on the temperature of the water sample.
Removal of suspended particles by sedimentation depends upon the size and specific gravity of those particles.
Suspended solids retained on a filter may remain in suspension if their specific gravity is similar to water while very dense particles passing through the filter may settle.
Sodium hydroxide and sodium chloride are both bases.
2. In a sedimentation process, the solid particles settled at the bottom of the container because they are heavier than water and are acted upon by gravity.
In the process of distillation, the condenser helps in the conversion of the vapor that goes inside it into liquid.
After filtering a mixture using a filter paper, there is more solute at the bottom of the container compared to the contents of the filter paper.
In the reaction between dry ferrous sulfate and dry potassium ferricyanide, no change is observed.…
Explain why different amounts of sugar might dissolve at different times.
Consider:
• which day the least sugar dissolve in which day the most sugar dissolved 
• what kind of cause less sugar to dissolve on some days
• what does student could do to his drink to make more sugar dissolve.
be sure to consider the completeness of your response, supporting details, and accurate use of terms. Your response should be 6 to 8 complete sentences.

- For the water quality evaluation (as learned in the lab), total dissolved solids (TDS) is one of the key parameters controlling the water quality.
