In this experiment you will
obtain an UNKNOWN containing KClO3. In a quantitative experiment, you will
determine the mass and volume of oxygen generated and the mass of UNKNOWN used.
From this you will be able to....... |
- Determine the Molar Volume of the Oxygen
generated by the catalytic decomposition of the UNKNOWN
|
- Determine the Per Cent of KClO3
in your UKNOWN based on the mass of Oxygen generated and the mass of the Unknown using the
equation:
|
...
2 KClO3 -------> 2 KCl +
3 O2
... |
Actually
this is two experiments. |
- From the Mass of Oxygen and
the Volume of Oxygen you will determine oxygen's Molar Volume at STP.
|
- From the Mass of Oxygen and the Mass of UNKNOWN you will determine the
% KClO3 in
the UNKNOWN.
