8S started their work on salt analysis with a little work on our old friend copper carbonate
First the mass of the copper carbonate was calculated
The the test tube was heated
While any gas given off had to bubble through limewater
If this went cloudy then it means carbon dioxide was released
The test tube needs to cool down
after heating
then the mass of the remaining copper oxide can be found
Plotting all of their results we found a good correlation between the two masses.
