1. Ch. 15 - Solutions I. How Solutions Form Definitions
Types of Solutions
Dissolving
Rate of Dissolving

2. A. Definitions Solution - homogeneous mixture
Solute - substance being dissolved
Solvent - present in greater amount

3. A. Definitions
Solute - KMnO4
Solvent - H2O

4. B. Types of Solutions Based on state of solvent.
All solid-liquid-gas combos are possible.
EX: dental amalgam (alloy of silver, mercury, etc.)
liquid solute, solid solvent
solid solution

5. C. Dissolving Solvation occurs at the surface of the solute
solvent particles surround solute particles (+/- attraction)
solute particles are pulled into solution

6. NaCl dissolving in water
C. Dissolving
NaCl dissolving in water

7. D. Rate of Solution Solids dissolve faster... more stirring
small particle size (increased surface area)
high temperature

8. D. Rate of Solution Gases dissolve faster... no shaking or stirring
high pressure
low temperature
