1. Chapter 22 Sect. 1: SOLUTIONS NOTES
Mixtures Review
A mixture is 2 or more substances that are combined together that can be separated by _____________ means (not chemically bonded together)
_______________mixtures – ____________ mixed mixtures, “_____________” composition throughout
______________ mixtures– ____________ mixed mixtures, “_____________” composition throughout
Solutions
Which type of mixture are solutions?
_____________________
Solutions have the same ____________, ____________, and ______________throughout them
We call solutions the “_____________________”
If a solution is made from a substance dissolved in ________, it is called an _________________solution

2. Solutes and Solvents
To create a solution, one substance must ____________ in another substance
____________– the substance _________________
When solids or gases are dissolved in liquids, they are considered to be the solutes
__________– the substance ___________________
When a liquid dissolves another liquid, the liquid that has the largest amount is considered to be the solvent
As a general rule of thumb, there is LESS _________ and MORE ______________in a solution

3. Nonliquid Solutions
Solutions do not always involve a solid or gas dissolving in a liquid
Solid dissolved in solid
i.e. __________________________________________
Gas dissolved in gas
i.e. ___________________________________________
Liquids dissolved in gas
i.e. ___________________
Gas dissolved in solid

4. Identifying Solutes and Solvents
For each example, identify the solute and the solvent:
Kool-Aid
Solute: _____________________
Solvent: _____________________
Sterling Silver (92.5% silver, 7.5% copper)
Styrofoam
Mountain Dew

5. How Substances Dissolve1.
They are attracted to each other because they have opposite charges (like a magnet) 2. 3.

6. Rate of Dissolving
What can you do to increase the rate at which solutes dissolve in solvents?
________________!
More solvent is brought in contact with the solutes, which cause the particles to dissolve more quickly
_________________
If you make larger solutes smaller, you are increasing the surface area of the crystals which allows the solvent to surround it more easily
This speeds up the movement of the particles which causes more of the solvent particles to bump into the solute particles
