Our science test is Wednesday. Study study study! Bonus: Know which acids and bases go with which formulas.... It's on the test so test your self on it.

suspension

mixture in which particles can be seen and easily seperated by settling and filrtation, also has different properties throughout

solution

well-mixed mixture, not seen particles, light goes through, same properties throughout,

solvent

part of solution present in the larger amount

solute

part of solution present in the smaller amount

break, become surronded by solvent

what happens to the particles of a solute in mixing?

colloid

mixture with small, undisolved particles which do not settle out, scatter light, not usually liquid, particles held together by something

freezing point

solutes lower the _________ of solvents

boiling point

solutes reaise the ____________ of solvents

dilute

only a little solute is dissolved

concentrated

more solute is dissolved

(amount of) solute to solvent

how to measure concentration... amount of ______ to _______

solubility

the measure of how well a solute can dissolve in a sovent at a given temperature

saturated (solution)

a solution that contains as much solute as possible at a given temperature

unsaturated (solution)

a solution that does not contatain as much solute as possible at a given temperature

temperature, pressure, type of solvent

3 different factors that effect the solubility of a substance

supersaturated (solution)

a solution that is holding more solute than it can normally hold at that temperature

sour

the way acids taste

metals

what acids react with

carbonates

what acids react with that makes carbondioxide

indicatore

a compound that changes color in the presence of an acid or a base

red

color acids turn litmus paper

bitter

taste of bases

slippery

how bases feel

blue

color bases turn litmus paper

no carbon dioxide

what bases don't make in reactions

hydrogen

ions that are produced in reactions of acids

hydroxide

ions that are produced in reactions of bases

pH scale

a range of values from 0 to 14 which rates acidic or basic properties of substances
