Acids, Bases, and Solutions Flashcards

Terms Definitions
base
tastes bitter
Acids
turn blue litmus red
what is a proton donor
base
colloid
A mixture containing small, undissolved particles that do not settle out.
Mixture
(chemistry) a substance consisting of two or more substances mixed together (not in fixed proportions and not with chemical bonding)
substance
matter that has the same composition and properties throughout the sample
Examples of Bases
soap, milk, milk of magnesia
unsaturated solution
if you still dissolve more solute
Solution
A homogeneous mixture made when one substance dissolves another.
define dissociation
porcess in which an ionic compound seperates into ions as it dissolves
pH
a value that indicated the acidity or alkalinity of a solution on a scale of 0-14, based on the proportion of H+ ions.
pH scale
describes how acidic or basic a solution is
supersaturated solution
a mixture that has more dissolves solute than is predicted by its solubility at a given temperature
indicator
a compound that changes color when in contact with an acid or a base
define saturated
soultion contains as nuch solute as it can hold at a given time
Solute
The part of a solution present in a smaller amount.
solvent
The part of a solution that is present in largest amount and dissolvs a solute.
describe a weak base
inoize or dissociats only slightly in water
7-11
concentrated solution
one that has a lot of solute dissolved in the same
Salt and Water
Adding and acid to to a base always results in these products
Water
7
Acid
A solution containing higher concentrations of H+ ions than pure water and a pH value below 7.
Bases
taste bitter, slippery, don't conduct electricity, recognized by an OH- ions
Suspension
-particles can be separated from the mixture by some form of filtration
ex: yoo hoo, orange juice
Adhesion
the molecular force of attraction in the area of contact between unlike bodies that acts to hold them together.
A base is a substance that tastes_______. It feels slippery.
bitter
pH scale
salt
measurement system used to indicate the concentration of hydrogen ions in solution: ranges from 0-14
any ionic compound that can be made from the neutralization of an acid with a base
neutralization
a reaction of acid with a base, yielding a solution that is not as acidic or basic as the starting solutions were
decreases
What happens to the solubility of a gas in water if the temperature goes up?
weak base
any base that does not dissociate completely in solution.
Some common acids are ___________.
hydrochloric, nitric, sulfuric, carbonic and acetic
saturated
all solute is dissolved, no more can be added
Solubility
A measure of how well a solute can dissolve in a solvent at a given temperature
acid rain
What is caused by the release of pollutants into the air and causes damage to statues, forests,and lakes?
Amphoteric
any species that can act as either an acid or a base
corrosive
the way in which acids react with some metals so as to eat away the metal
Polyprotic Acid
an acid that can donate more than one proton per molecule
pH in your small intestine
pH is close to 8 so it's basic
/ 38
