Physical Science | Chapter 6 | Acids, Bases, and Solutions

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.
STUDY
PLAY
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
hydrogen
what "H" stands for in "pH"
0
most acidic on the pH scale
14
most basic on the pH scale
7
neutral on the pH scale
5
pH of normal rainfall (approximite)
4
pH of acid rainfall (approximite)
neutralization
reaction between acids and bases
salt
any compound made by the reactions of acids and bases
water and a salt
products of neutralization
