2. Why was Copper Oxide added in excess? Why is this important?
It’s important to have excess copper oxide within the experiment as it shows that it’s all fully reacted experiment, the procedure has been completed. It shows that all of the sulphuric acid has been used up, if the sulphuric acid was in excess then it will be extremely dangerous and it would be hard to take out, yet the copper oxide is very easy to take out.
3. Which physical feature is distillation using to separate out the mixture?
The distillation process uses the boiling point of 100°C to separate out the chemicals.
4. Explain how
you determine whether your distilled liquid is water? Provide photographic evidence?
During the experiment it will be noticeable that when the thermometer reaches 100°C the distilled water will fall from the apparatus into a beaker.
