By using the volumes of each (both the known and unknown), a chemist can
determine the concentration of the unknown.
V=volumes (must be in the same units)
Ma= concentration of the H+ (**note 2M H2SO4
is really 4M H+)
Mb= concentration of OH- (2M Ca(OH)2 is
really 4M OH-)
Past regents questions
June 2010-28 During which process can 10.0 milliliters of a 0.05 M HCl(aq)solution
be used to determine the unknown concentration of a given volume of NaOH(aq)solution?
(1) evaporation (3) filtration
(2) distillation (4) titration
The data collected from a laboratory titration are used to calculate the
(1) rate of a chemical reaction
(2) heat of a chemical reaction
(3) concentration of a solution
(4) boiling point of a solution
A student completes a titration by adding 12.0 milliliters of NaOH(aq)of
unknown concentration to 16.0 milliliters of 0.15 M HCl(aq). What is
the molar concentration of the NaOH(aq)?
(1) 0.11 M (3) 1.1 M
(2) 0.20 M (4) 5.0 M
