Making another salt
Aim:
To make copper sulfate crystals (salt) by neutralising copper oxide (base) with a sulfuric acid (HSO)
Observations: (write an observation for each key stage of the process - full sentences please)
1. when we added the copper oxide to the acid, the liquid turned blue and the copper oxide dissolved.
2. the liquid was clear blue after we filtered it.
3. when the water evaporated (4 days later) there were crystals
Results:
Add 3 photos for the final stages of the experiment to illustrate the process.
