•Give
an example of a heterogeneous mixture. How do you know it is
heterogeneous. Is there any way to make the mixture homogenous? Why or why
not?
•Learning
Target
I will learn about factors that change
the rate a solute dissolves in a solvent.
•Criteria
for Success
I will be able to explain some
of the factors that can change the rate at which a solute dissolves in a
solvent.
•Solution
A homogeneous mixture where one substance
is dissolved in the other.
•Solvent
a liquid, solid, or gas that dissolves
another solid, liquid, or gaseous solute
When you dissolve salt in water, water is
the solvent.
•Solute
A substance dissolved in another substance.
When you dissolve salt in water, salt
is the solute.
•There
are many different factors that can change how fast or slow a solute dissolves
in a solvent.
•We
are going to make some of these mixtures in the lab! Remember to follow all lab
safety rules! Do not eat or smell anything, wear your goggles the whole time,
listen to my directions!!!
•Reflection
Explain one factor that can change the
rate at which a solute dissolves in a solvent
