Question

You have some bottles of chemicals whose labels have fallen off: HC,H,0, (aq), AICI, (aq), and C,H,,0, (aq). You are going to
identify them by measuring the conductivity.
First, you measure the conductivity of some known substances to find the electrolyte ranges for your conductivity probe:
hydrocyanic acid (HCN) 126 µS/cm
0.01 M Nacl
ethanol (C,H,0)
phosphoric acid (H,PO,) 247 µS/cm
From these measurements, you determine that
ed
00
ion
5643 µS/cm
63 μS/cm
nonelectrolyte conductivities range from 0 to
uS/cm
weak electrolyte conductivities range from
to
uS/cm
strong electrolyte conductivities are
uS/cm and higher.
You take a sample from one of the bottles and it measures 76 uS/cm.
This bottle should be labeled m
