You will need more Zn since some Zn will
react with the excess sulfuric acid.
During this experiment, students dissolve the CuO using
sulfuric acid. What effect, if any, will using excess sulfuric
acid have on the next step of adding Zn to the filtrate and

Some reactions are slow, but heating them often speeds
them up. What is the best way to do that for experiment 3b.
You should add only as much zinc as you
need to make the solution colorless.
The manual tells you to add zinc to your solution. How
should you do this.
Filter the solution to collect the tiny
Some students produce really small particles of copper and
