Three 10 g samples of sugar are represented below.
Sample A dissolves in water more slowly than sample B.
Sample B dissolves more slowly than sample C.
Which of the following best explains why sample A dissolves more slowly than the other two?
It has the most volume.
It has the smallest surface area.
It has the largest number of sugar molecules.
It has the fewest bonds between sugar modules.
You can make a solid solute dissolve more quickly in a solvent by
adding more solute.
adding ice.
heating the solvent.
removing some solvent.
A solvent is
a mixture
a liquid
A substance which dissolves a solute
anything that can mix
A solution that contains all of the solute it can hold at a given temperature is
diluted.
saturated.
supersaturated.
unsaturated.
The ability of a solute to be dissolved is called its
nature
mixture
solubility
solvent
How can you create a supersaturated solutions?
Dissolve lots of solvent in the solute
Dissolve a small amount solute in the solvent
Dissolve more solute in the solvent than you should be able to by heating the solvent
Dissolve a super amount of solvent in the solute
A technican prepared a solution by heating 100 mL of distilled water while adding KCl crystals until no more KCl would dissolve. She then capped the clear solution and set it aside on the lab counter. After several hours she noticed the solution had become cloudly and some solid had settled to the bottom of the flask. Which statement best describes what happened?
As the solution cooled, evaporation of water increased the KCl concentration beyond its solubility.
Water molecules, trapped with the KCl crystals, were released after heating.
At lower temperatures the solubility of KCl decreased and recrystallization occurred.
At increased temperatures the solubility of KCl increased and remained too high after cooling.
