Different ways that water mixes with different substances

2. Chemistry of Water Did you know that water…. covers 75% of the earth.
is essential to all life forms.
makes up about 60% of your weight.
is a very small molecules.

3. Properties of the water molecule
1. water is a polar molecule
It has a positive and negative side
Oxygen has a greater electronegativity than hydrogen. (it pulls harder on the electrons)

4. A. Cohesion is the attraction between water molecules
2. Hydrogen Bonds – the negative side of one water molecule attracting to the positive side of another
A. Cohesion is the attraction between water molecules
Surface Tension
Capillary Action
Surface Tension

5. B. Adhesion is the attraction between water and a different substance
C. Heat capacity
It takes a lot of heat to break through those hydrogen bonds…so water can absorb a lot of heat

6. 3. Water Mixed with other substance
a. Solution is a mixture; the particles are dissolved and evenly distributed throughout the liquid
Solution
Solvent – dissolves the solute
Solute – gets dissolved

7. Salt dissolving (ionizing) in water

8. Emulsion is a mixture of two unbendable liquids
Suspension is materials in water that DO Not dissolve , but do separate into tiny particles
Liquid medicine
Blood
Muddy water
Emulsion is a mixture of two unbendable liquids
Oil and water
