Write the reaction equation: Ca (OH) 2 -CaCO3- CaH (CO3) 2- CaCO3-CaO-CaCl
July 17, 2021 | education
| We obtain the following reaction equations corresponding to the chain of transformations given below:
Ca (OH) 2 → CaCO3 → CaH (CO3) 2 → CaCO3 → CaO → CaCl2:
1) Ca (OH) 2 + Na2CO3 → CaCO3 + 2NaOH;
2) CaCO3 + CO2 + H2O → Ca (HCO3) 2;
3) Ca (HCO3) 2 → CaCO3 ↓ + CO2 + H2O;
4) CaCO3 → CaO + CO2;
4) CaO + 2HCl → CaCl2 + H2O.
