What is water?
A chemical compound that is made up of 2 hydrogen ions and 1 oxygen ion.
Five body processes in which water is essential:
Cirrculation, Absorbtion, Growth, Excretion, Digestion
Properties of water

-Expands when it freezes

-Ice floats on water b/c it is less dense than water

-Has a high specific heat

-Called the universal solvent

-Freezing point is 0 degrees celcius 

Can either speed up or slow down a chemical reaction and won’t undergo any permanant changes or be used up.
Material used to dissolve something (water in saltwater)
Material that is dissolved (Salt in saltwater)

-Particles are evenly dissolved (uniform)

-Particles are invisible

-Particles don’t settle out

Three factors that affect the rate of dissolving
Tempature, nature of substance, and pressure
Liquids and solid are more soluable at _____ tempatures.
Gases are more soluable at ______ tempatures.
Carbon Dioxide is dissolved in soda under what conditions?
Lower temperatures and high pressure.
Solids become more soluable in water as temperatures _______.
Three things that inrease the rate of dissolving.

-Grinding the solute (solid)

-Shake the solution; mix it together

-Increase the temperature of the solvent

How do solutes effect the boiling point of a substance?
Solutes raise the boiling and lower the freezing point.

Non-uniform mixture of tiny, insoluable solid particles distributed throughout a liquid or gas.

Ex. Muddy water, oil based paints

Properties of a suspension

-Particles are visible

-Particles can be removed by filtration

-Particles will settle out if left standing


Special kind of suspension where particles are medium sized, so they don’t dissolve, but are evenly, distributed.

Ex. Jello, Milk

Properties of a colloid

-Particles are invisible

-few or none of the particles can be removed

-few or none of the particles will settle out on standing

Why is water shortage a problem?

1.We use more water then we need

2.Water is needed for body function

3.When water is polluted plants and animals die

How much of earths surface does water cover?
70% of earths surface
When supersaturated are shaken to settle the excess solute out.
How much of earths water is saltwater?
Making fresh water into seawater.
Dilute solution
Contians a large amount of solvent compared to a relatively small amount of solute.
Concentrated Solution
Contains a comparatively large amount of solute dissolved in a small amount of solvent.
Unsaturated Solution
A solution in which the solvent has less solute dissolved in it than it can hold at a given temperature and pressure.
Saturated Solution
A solution in which the solvent has dissolved all the solute it can dissolve at a given temperature and pressure.
Supersaturated Solution
A solution that contians more dissolved solute than it would normally hold at a given tempature and pressure.

-is less dense than air

-is “flamable air”

Carbon Dioxide

-density is 1.8X10-3 and is more dense than air

-Somothers fire

-Solid carbon dioxide is dry ice

Commom gas that dissolves very well in water?


Carbon dioxide and oxygen are also slightly soluble in water.

How is acid rain formed?
Sulfur dioxide dissolves in rain water.
Problems with acid rain:

-Dissolves surface of stone

-Damages or kills plants

-Harmful to animals

Formula for finding concentration when given data:

ED+Solid;;;;;;; ED+Solution

-ED;;;;;;;;;;;;;;- ED+Solid;;;

Solid;;;;;;;;;;;;;; Mass of water=Volume of water



Mass of solid

Volume of water

What is 11g in 33.3333cc of water in 100cc?
Large bodies of water take along time to change temperature because _______.
