Why Is Copper Oxide Added In Excess
1. Write out the balanced symbol equation for the reaction between copper oxide and sulphuric acid:
H2SO4(aq) + CuO(s) CuSO4(aq) + H2O(l)
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
H2SO4(aq) + CuO(s) CuSO4(aq) + H2O(l)
