objective 1
1 solutions are made up of a solute and a solvent an example is sugar and water colloids have larger particles than solutions an example is milk suspensions have the largest particles of all settle out quickly and never really mix an example is tea and water
2 the particles leave each other and join the solvent
3 the solute lowers the freezing point and raises the boiling point
4 you would make a solution because the particlesdissolve and mix well
5 see 3
objective
1 concentration is measured by how much of a substance is in another substance
2 it helps you figure out what a substance is
3 temperature pressure and type
4 it depends on heat to break the bonds
5 you can do tests to see how much of a substance can be dissolved in it
objective 3
1 conduct electricity, are sour, reacts with base, and react with active metals
2 conduct electricity, bitter tasting, react with acids, and feel slippery
3 bases=blue acids=red
4 acids taste sour so if acid is in the food it will taste sour
5 chemicals inside fertilizer could get on your hands
objective 4
1 the ion is H+
2 acid makes hydrogen ions in water and bases create hydroxide ions
3 it is an acid and breaks up HNO3 into H+NO3
4 it tells you the amount of hydrogen ions
5 when the ph number is lower the number of hydrogen ions is higher
objective 5
1 stomach and small intestine
2 stomach acid breaks down food and the small intestine digests fats and carbs
3 it would take longer because of the big food bits
4 the mouth is acidic because it breaks down food
5 acids break things down and acids and bases help digest food
