Parts of Solutions
In saltwater, what is the solute?
Salt
True or false: Liquid solutions can only have liquid solutes.
False
A ____________________ solution has a high amount of solute.
concentrated
If you put sugar cubes or loose sugar crystals into tea, which would dissolve more quickly?
The loose sugar crystals
What does homogeneous mean?
The same all the way through
True or false: A solution can have more than one solute
True
Coca-Cola is an example of a __________________ solution.
liquid (or aqueous)
A _____________________ solution has a low amount of solute.
dilute
Polar substances only dissolve ______________ substances.
polar
A solution is a _____________________ mixture of two or more substances.
homogeneous
True or False: Only liquids can be solvents
False
gaseous
____________________ measures the amount of solute dissolved in a certain amount of solvent.
Concentration
What are three ways to speed up dissolving?
1. Create movement
2. Increase the temperature of the solvent
3. Increase the surface area of the solute
What is an example of a non-polar substance?
Oil
The __________________ is the part of a solution that is dissolved into something else.
solute
Aqueous
_______________ is the amount of solute needed to bring a solution to saturation.
Solubility
A solution that has more solute than the solvent would normally be able to dissolve is called a _________________ solution.
supersaturated
What does it mean for something to be a polar substance?
It is made of molecules that share their electrons unequally, which means they will have positively and negatively-charged regions.
The __________________ is the part of a solution that is present in the largest amount and dissolves something else.
solvent
A ring made of an alloy of different kinds of metals is an example of a ______________ solution.
solid
____________________ is the point at which a solution won’t dissolve anything else.
Saturation
How can you create a solution with more solute than the solvent would normally be able to dissolve?
1. Heat up the solvent
2. Add as much solute as possible
3. Cool down the solvent
Is dissolving something an example of a physical or chemical change? Why?
It is a physical change because the substances keep their original characteristics and chemical bonds are not created or broken.
