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 |
Catalyst |
Can either speed up or slow down a chemical reaction and won't undergo any permanant changes or be used up. |
Solvent |
Material used to dissolve something (water in saltwater) |
Solute |
Material that is dissolved (Salt in saltwater) |
Sloutions |
-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. |
Higher |
Gases are more soluable at ______ tempatures. |
Lower |
Carbon Dioxide is dissolved in soda under what conditions? |
Lower temperatures and high pressure. |
Solids become more soluable in water as temperatures _______. |
Increase |
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. |
Suspension |
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 |
Colloid |
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 |
Seeding |
When supersaturated are shaken to settle the excess solute out. |
How much of earths water is saltwater? |
97% |
Desalinization |
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. |
Hydrogen |
-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 |
