How to get from CuO – CaSO3?
| September 11, 2021 | education
The transformation of one substance into another is based on the chemical properties of the compounds.
1. The starting material is copper oxide, and the final substance is calcium sulfite. So we need to decompose the oxide:
4CuO = 2Cu2O + O2. Temperature over 1100 ° C.
2. Since sulfite is a compound with sulfur, we will oxidize sulfur to oxide.
S + O2 = SO2.
3. Let’s introduce calcium into the compound.
The calcium hydroxide will react with sulfur oxide to form sulfite.
SO2 + Ca (OH) 2 = CaSO3 + 2H2O.
