A solution that contains all of the solute it can hold at a given temperature is
diluted.
saturated.
supersaturated.
unsaturated.
The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its
concentration.
density.
dilution.
solubility.
A solution is defined as
A mixture of oil and water
A mixture where a substance is dissolved
A mixture that contains two solids
None of the above
A solution is made up of two components. The first is the solute. What is the solute?
The substance that dissolves
The substance that does the dissolving
The liquid substance
None of the above
A solvent is
a mixture
a liquid
A liquid substance which dissolves a solute
anything that can mix
Choose from the list below, an example of a solvent
sand
sugar
salt
water
The ability of a solute to be dissolved is called its
nature
mixture
solubility
solvent
Solute + Solvent =
Mixture
colloid
suspension
solution
Select all the factors which can affect the solubility of a substance
temperature
size of solute or the surface area of the solute
the amount of stirring
colour of the solute
Which method below is used to get back the salt from a solution of salt and water?
Condensation
Photosynthesis
Freezing
Evaporation
As the temperature increases, the rate at which the solute dissolves ____________
remains the same
decreases
also increases
none of the above
What do you call a solution that contains less than the maximum amount of solute that is capable of being dissolved?
unsaturated solution
saturated solution
supersaturated solution
insoluble solution
Which of the following best describes a supersaturated solution?
a solution that contains the maximum amount of solute that is capable of being dissolved
a solution that contains less than the maximum amount of solute that is capable of being dissolved.
a solution that contains more than the maximum amount of solute that is capable of being dissolved.
none of the above
Why does salt dissolves faster in water if you stir it?
Solvent and solute particles move faster and allow the solute to fill up empty spaces between solvent particles
Solvent and solute particles gain more heat energy to move in empty spaces inbetween them
Why fine salt dissolves faster bin water compared to coarse salt?
Fine salt has bigger total surface area exposed to water
Fine salt has smaller total surgace arra exposed to water
In which beaker does salt dissolves faster?
Hot water
Room temperature
Ice watet
Why does salt dissolves faster in hot water?
Hot water hive high kinetic energy to solvent and solute perticles
More collision between solute and solvent particles
Higher temperature gives more surgace area to the solute
Higher temperature, higher rate of solubility
True
False
Increasing the temperature will increase the kinetic energy of particles, therefore increasing the collisions between particles.
false
true
