2. ACID + BASE  SALT + WATER
Neutralization Reactions (REVIEW)
Neutralization –
rxn of acid and base making a salt and water
ACID + BASE  SALT + WATER =
HCl + NaOH  NaCl + HOH
H2O

3. Titration
The analytical technique used to calculate the moles in an unknown soln.
mass % (g /gtotal)
molarity (mol/L)
molar mass (g/mol)
buret
titrant
known vol. (V)
known conc. (M)
Safari Montage (2 min) Titration
analyte
known vol. (V)
unknown conc. (M)
(or moles)

4. equivalence point,(Veq):
end point:
indicator color change persists
equivalence point,(Veq):
equal stoichiometric amounts react completely
HBr + NaOH 
mol Acid =
mol Base
2 HA + Ca(OH)2 
H2SO KOH 
