titration
an analytical technique used to determine the unknown concentration of a soln by reacting it with a soln of known concentration
type of volumetric analysis
standard soln/titrant
soln of known concentration
analyte
solution containing thes ubstances being analyzed
equivalence pt
point in titration when mols titrant stoichiometrically = mols analyte
(ex if there’s a 2 coefficient, then mols need to be multiplied by 2)
both reagents completely consumed
end pt of titration
end of titration indicated by a color change
strong acid strong base pH
pH=7
weak acid strong base pH
pH >7
weak base strong acid pH
pH<7
ideally what should end pt equal
equivalence pt
how to choose an indicator
pH transition range (pka +- 1) amtches pH change around eq
titration curve
a graph that gives pH of a solution at diff stages of titration
helps us understand the acid-base rxn occurring during the titration
