Worksheets8.1 Formation of Solutions
Total questions: 12
Worksheet time: 14mins
What are three ways that substances can dissolve in water?
dissociation
melting
dispersion
ionization
suspension
What physical properties of a solution differ from those of its solutes and solvent?
boiling point
density
conductivity
mass
melting point
How does the formation of a solution involve energy?
There is no energy involved in the formation of a solution.
Energy is required to break the bonds between solutes and the bonds between solvents.
Energy must be injected at the right time for the solution to form.
Energy is released or absorbed as new attractions form between the solute and solvent.
What factors affect dissolving rates?
mass
volume
temperature
surface area
stirring/shaking
Suppose you put equal amounts of pure water and salt water into separate ice cube trays of the same size and shape. When you put both trays in the freezer, what would you expect to happen?
The pure water would freeze faster than the salt water because the salt would lower the freezing point of the water.
The salt water would freeze faster than the pure water because the salt raises the freezing point of the water.
They would freeze at the same rate because the addition of a solute doesn't change the freezing point of water.
The pure water would freeze and the salt water would not.
The parts of a solution are the
salt and vapor.
solvent and solid.
solute and water.
solvent and solute.
In a solution, the solute is the substance that
dissolves in the solvent.
is in the greatest quantity.
is the liquid.
is the solid.
Sugar dissolves in water through
ionization.
dissociation.
neutralization.
dispersion.
Ionic compounds produce ions in solution by
ionization.
dissociation.
evaporation.
dispersion.
The process by which some molecular compounds dissolve in water to form ions is
ionization.
dissociation.
neutralization.
dispersion.
The boiling point of a liquid solution is
the same as the boiling point of the solvent.
the same as the boiling point of the solute.
higher than the boiling point of the solvent.
lower than the boiling point of the solvent.
Why might the temperature of water increase when a solution forms?
The solute increases the boiling point of the water.
The solvent decreases the melting point of the water.
More energy is absorbed when the solution forms than is released when the solute and solvent molecules separate and break apart.
More energy is released when the solution forms than is absorbed when the solute and solvent molecules separate and break apart.
