Acid + Base =
Salt + Water
Strong acids and bases..
Ionize completely
Dilute does'nt mean _____, and concentrated does'nt mean _____.
Arrhenius concept
acids produce hydrogen ions in aqueous solution and bases produce hydroxide ions in solution
Bronsted-Lowry model
acid is a proton donor and base is a proton acceptor
species acts as an acid or base
acids and bases that have water removed
acidic anhydrides
-Diprotic Acid
-Triprotic acid
Acid dissociation constant
only for weak acids

Ka= [CA][CB]
The larger the Ka, the
stonger the acid.
organic acids are
very weak
Oxygens have to outnumber
the oxygen by two or more.
Kw constant
1.0 x 10 ^-14
Process of determining the concentraion of an unknown substance by use of a standard solution.
Titration instrument is a
Acids and bases destroy each others chemical properties
The products of Neutralization are salt and water. The salt is..
a cation from the base and an anion from the acid
Equivilance point-
when the number of hydrogen ions equals the number of hydroxide ions (when an acid and base are mixed)
Point at which a color change is noted
End point
The point of neutralization is..
the End point
Step one for titration problems
(1) Calculate moles used in neutralization process (MxV)
Step 2 for titration problems
(2) Calculate the moles that can be neutralized for the unknown by the given (Stoichiometry, Balenced Equation)
Step 3 for titration problems
(3) Go back to formula
(M1V1 = M2V2) and insert calculation for given moles
If salt ions (cations) donate H+ to water then...

anions accept H+ from water then...
aqueous solution is acidic;

aqueous solution is basic

solutions that resist changes in pH when limited amounts of acid or bases are added

aquariums, blood
Buffers can also be
weak acids and a salt of weak acid
