The smaller the particle size the faster the rate of dissolution (rate of dissolving).
True
False
True or False

True
False
Jackson is making dinner and is trying to dissolve salt into a pot of water. The salt is dissolving slowly. What should Jackson do to speed up the rate of dissolving?
He should put larger salt particles in the water.
He should heat the water to a higher temperature.
He should completely stop stirring the pot of water.
He should slow down the speed he is stirring the pot.
What combination would dissolve a solid solute the fastest?
high temperature, no stirring
no heat, no stirring
sugar cube, no heat
high temperature, stirring
Stirring the solution increases the rate of dissolution (rate of dissolving).
True
False
The sugar cubes are called the
solute
solvent
The water is called the
solvent
solute
In which cup will the salt dissolve more slowly?
A solution with high amount of solute
concentrated
saturated
unsaturated
diluted
What kind of mixture is shown in the picture?
Homogeneous
Heterogeneous
What kind of mixture is shown in the picture?
Homogeneous
Heterogeneous
What are the 3 factors that affect rate of dissolution (how fast things dissolve)?
temperature, wind, surface area
temperature, agitation, surface area
emotions, attitude, language
temperature, sound, surface area
What is the definition of temperature?
The measure of hotness or coldness
A homogeneous mixture
stirring
the area of the chemical components used in a reaction
What is the definition of agitation?
The measure of hotness or coldness
A homogeneous mixture
stirring, shaking, mixing
the area of the chemical components used in a reaction
What is the definition of surface area?
The measure of hotness or coldness
A homogeneous mixture
stirring, shaking, mixing
the area of the chemical components used in a reaction
How does temperature affect rate of dissolution?
high (hot) temperature dissolves slowly
high (hot) temperature dissolves faster
low (cold) temperature dissolves faster
How does agitation affect rate of dissolution?
It does not affect it
agitation increases the rate of dissolution (dissolves faster)
agitation decreases the rate of dissolution (dissolves slower)
How does surface area affect rate of dissolution?
It does NOT affect rate of dissolution
higher surface area (more little pieces) dissolves faster
lower surface area (more big pieces) dissolves faster
What is the best definition of rate of dissolution?
the measure of hotness or coldness
stirring
the area of the surface of the solute
the speed at which a solute dissolves in a solvent to form a solution
