**On Heating, which of the following releases CO2 most easily: MgCO3, CaCO3, K2CO3, Na2CO3?**
**Introduction:**
When certain metal carbonates are heated, they undergo thermal decomposition to produce carbon dioxide gas (CO2) and a metal oxide. The ease with which a metal carbonate decomposes depends on the stability of the metal carbonate and the strength of the metal-carbonate bond.
**1. MgCO3 (Magnesium Carbonate):**
- Magnesium carbonate is a relatively stable metal carbonate.
- On heating, it undergoes thermal decomposition to form magnesium oxide (MgO) and carbon dioxide gas (CO2).
- The decomposition of magnesium carbonate requires a high temperature, around 600-700°C.
- Therefore, MgCO3 does not release CO2 easily compared to other carbonates in the list.
**2. CaCO3 (Calcium Carbonate):**
- Calcium carbonate is a commonly found metal carbonate.
- On heating, it undergoes thermal decomposition to form calcium oxide (CaO) and carbon dioxide gas (CO2).
- The decomposition of calcium carbonate occurs at a lower temperature compared to magnesium carbonate, around 825-900°C.
- Therefore, CaCO3 releases CO2 more easily compared to MgCO3.
**3. K2CO3 (Potassium Carbonate):**
- Potassium carbonate is an alkali metal carbonate.
- On heating, it undergoes thermal decomposition to form potassium oxide (K2O) and carbon dioxide gas (CO2).
- The decomposition of potassium carbonate occurs at a relatively low temperature, around 400-500°C.
- Therefore, K2CO3 releases CO2 more easily compared to both MgCO3 and CaCO3.
**4. Na2CO3 (Sodium Carbonate):**
- Sodium carbonate is another alkali metal carbonate.
- On heating, it undergoes thermal decomposition to form sodium oxide (Na2O) and carbon dioxide gas (CO2).
- The decomposition of sodium carbonate occurs at a lower temperature compared to potassium carbonate, around 300-400°C.
- Therefore, Na2CO3 releases CO2 more easily compared to all the other carbonates in the list.
**Conclusion:**
Among the given metal carbonates, Na2CO3 (Sodium Carbonate) releases CO2 most easily upon heating. The order of ease of CO2 release is as follows: Na2CO3 > K2CO3 > CaCO3 > MgCO3.

**Conclusion:**
Among the given metal carbonates, Na2CO3 (Sodium Carbonate) releases CO2 most easily upon heating. The order of ease of CO2 release is as follows: Na2CO3 > K2CO3 > CaCO3 > MgCO3.
