During an experiment about the rate of dissolving you test temperature. In one beaker you use room temperature water, one beaker you use hot water and the last beaker you use ice water. In what order would the beakers dissolve the solute from slowest to fastest?
hot, cold, room temperature.
cold, hot, room temperature.
cold, room temperature, hot.
hot, room temperature, cold.
In this model what is being changed about the solution?
There is more solvent being added making it concentrated.
There is more solute being added making it concentrated.
There is heat being added to speed up the rate of dissolving.
There is nothing special about this model.
The picture shows how you might change an variable in an experiment about what affects the rate of dissolving. What results do you expect to see?
A will dissolve slowest because it has the largest number of particles.
D will dissolve slowest because it has the smallest surface area.
All pieces will dissolve at an equal rate.
C will dissolve slowest because it has the most bonds between sugar molecules.
Look at the solubility curve - as a GENERAL rule (that means there are exceptions, as always, in science) what trend can be states about how temperature affects the solubility of the compounds shown.
Temperature has NO affect.
The relationship is inversely proportional - as temperature increases, the solubility decreases.
The relationship is directly proportional - as temperature increases, the solubility increases.
It varies - the solubility will increase and then decrease when it reaches a certain temperature.
If you were testing what might affect the rate of dissolving of sugar, you could test the affect of agitation (shaking, stirring, etc). Which of the following BEST explains how this will change how fast the solute will dissolve.
Stirring the solution exposes the solute to fresh solvent more quickly.
Stirring helps more solvent evaporate.
Stirring causes more ions to precipitate out of solution.
Stirring equalizes the water temperature.
