Laboratory Work №1

Qualitative detection of
carbon,
hydrogen,
chlorine
in organic compounds

PROCEDURE
1. Put copper (II) oxide and paraffin into the test

tube, then heat it carefully until paraffin melts and
shake the test tube.
2. Place the test tube into the laboratory iron stand
and add some copper (II) sulfate
3. Close the test tube by a bent delivery test tube the
other end of which is dipping into lime water
contained in flame.

When mixture of paraffin and copper (II) oxide
is heated alkanes are oxidized to carbon
dioxide and water. Water forms hydrate with
copper (II) sulfate which has blue color.
Copper (II) oxide is reduced to red copper.
So in paraffin hydrogen exists.

Your observations
• Copper (II) oxide reduced to copper, so we observe
change in color from black to red.
C23H48 +70 CuO -> 23 CO2 + 24H2O + 70 Cu
• Colorless copper (II) sulfate changed its color to blue
because of formation of copper (II) sulfate pentahydrate.
CuSO4 + 5H2O -> CuSO4 * 5H2O
• Carbon dioxide formed as a result of reaction gives
precipitate of the carbonate by passing into limewater
solution.

Qualitative detection of
carbon,
hydrogen,
chlorine
in organic compounds

PROCEDURE
1. Put copper (II) oxide and paraffin into the test

tube, then heat it carefully until paraffin melts and
shake the test tube.
2. Place the test tube into the laboratory iron stand
and add some copper (II) sulfate
3. Close the test tube by a bent delivery test tube the
other end of which is dipping into lime water
contained in flame.

When mixture of paraffin and copper (II) oxide
is heated alkanes are oxidized to carbon
dioxide and water. Water forms hydrate with
copper (II) sulfate which has blue color.
Copper (II) oxide is reduced to red copper.
So in paraffin hydrogen exists.
