Reactions of CaO with Various Substances

When calcium oxide (CaO), also known as quicklime or burnt lime, reacts with different substances, various chemical reactions occur. Let's explore the reactions of CaO with the following substances:

1. H2 (hydrogen gas): - When CaO reacts with H2, it forms calcium hydride (CaH2) [[1]]. - The reaction equation is: CaO + H2 → CaH2.

2. HCl (hydrochloric acid): - CaO reacts with HCl to produce calcium chloride (CaCl2) and water (H2O) [[2]]. - The reaction equation is: CaO + 2HCl → CaCl2 + H2O.

3. SO3 (sulfur trioxide): - CaO reacts with SO3 to form calcium sulfate (CaSO4) [[3]]. - The reaction equation is: CaO + SO3 → CaSO4.

4. CuCl2 (copper(II) chloride): - When CaO reacts with CuCl2, it forms calcium chloride (CaCl2) and copper oxide (CuO) [[4]]. - The reaction equation is: CaO + CuCl2 → CaCl2 + CuO.

5. Na2O (sodium oxide): - CaO reacts with Na2O to produce calcium oxide (CaO) and sodium oxide (Na2O) [[5]]. - The reaction equation is: CaO + Na2O → CaO + Na2O.

6. Fe(OH)3 (iron(III) hydroxide): - When CaO reacts with Fe(OH)3, it forms calcium hydroxide (Ca(OH)2) and iron oxide (Fe2O3) [[6]]. - The reaction equation is: CaO + 2Fe(OH)3 → Ca(OH)2 + Fe2O3.

7. Al (aluminum): - CaO does not react with aluminum under normal conditions.

8. HNO3 (nitric acid): - CaO reacts with HNO3 to produce calcium nitrate (Ca(NO3)2) and water (H2O) [[7]]. - The reaction equation is: CaO + 2HNO3 → Ca(NO3)2 + H2O.

9. KOH (potassium hydroxide): - CaO reacts with KOH to form calcium hydroxide (Ca(OH)2) and potassium oxide (K2O) [[8]]. - The reaction equation is: CaO + 2KOH → Ca(OH)2 + K2O.

10. Li2SO4 (lithium sulfate): - CaO reacts with Li2SO4 to produce calcium sulfate (CaSO4) and lithium oxide (Li2O) [[9]]. - The reaction equation is: CaO + Li2SO4 → CaSO4 + Li2O.

11. K2CO3 (potassium carbonate): - CaO reacts with K2CO3 to form calcium carbonate (CaCO3) and potassium oxide (K2O) [[10]]. - The reaction equation is: CaO + K2CO3 → CaCO3 + K2O.

12. Mg (magnesium): - CaO does not react with magnesium under normal conditions.

13. P2O5 (phosphorus pentoxide): - CaO reacts with P2O5 to produce calcium phosphate (Ca3(PO4)2) [[11]]. - The reaction equation is: 3CaO + P2O5 → Ca3(PO4)2.

14. O2 (oxygen gas): - CaO does not react with oxygen gas under normal conditions.

15. CH4 (methane): - CaO does not react with methane under normal conditions.

16. NaNO3 (sodium nitrate): - CaO reacts with NaNO3 to produce calcium nitrate (Ca(NO3)2) and sodium oxide (Na2O) [[12]]. - The reaction equation is: CaO + 2NaNO3 → Ca(NO3)2 + Na2O.

17. Cu (copper): - CaO does not react with copper under normal conditions.

18. (NH4)2SO4 (ammonium sulfate): - CaO reacts with (NH4)2SO4 to produce calcium sulfate (CaSO4) and ammonium oxide (NH3) [[13]]. - The reaction equation is: CaO + (NH4)2SO4 → CaSO4 + 2NH3 + H2O.

19. Br2 (bromine): - CaO does not react with bromine under normal conditions.
