Question
1. ACID-BASE TITRATIONS
Four solutions of unknown HCI concentration are
titrated with solutions of NaOH. The following table
lists the volume of each unknown HCl solution, the
volume of NaOH solution required to reach the
equivalence point, and the concentration of each
NaOH solution. Calculate the concentration (in M) of
the unknown HCl solution in each case.
HCI Volume (mL)
NaOH Volume (mL)
[NAOH] (M)
(a) 25.00 mL
28.44 mL
0.1231 M
(b) 15.00 mL
21.22 mL
0.0972 M
(c) 20.00 mL
14.88 mL
0.1178 M
(d) 5.00 mL
6.88 mL
0.1325 M
