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. 2. Hydrogen Bonds – the negative side of one water molecule attracting to the positive side of another

5. Cohesion – the attractions between like molecules, so water to water
One example is Surface tension

6. another example is Capillary Action

7. B. Adhesion is the attraction between water and a different substance

8. Heat Capacity – the ability to absorb a lot of heat with out changing temperature

9. Mixture – two or more substances blended together

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

11. Salt dissolving (ionizing) in water

12. 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
HYDROPHOBIC – something that does not mix with water
