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 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 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
