Explanation:
The substance which is used for white washing is Calcium oxide (CaO).
1. Heating of marble
Chip of marble (calcium carbonate, CaCO3) being heated by the flame of a bunsen burner to produce quicklime (calcium oxide, CaO) and carbon dioxide gas (CO2).
Marble (CaCO3) + heat --> Lime (CaO) + CO2
2. formation of solution of P
Ca + O --> CaO
CaO + H2O --> Ca(OH)2
Calcium hydroxide is also known by many other names like hydrated lime, slack lime, pickling lime, or caustic soda.
I hope you find the answer useful.
