Question:
On heating which of the following releases ${CO_2}$ most easily ?
On heating which of the following releases ${CO_2}$ most easily ?
Updated On: Jul 13, 2024
- ${MgCO3 }$
- ${CaCO3 }$
- ${K2CO3 }$
- ${Na2CO3 }$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The correct option is(A): MgCO3
Thermal stability order
\({K_2CO_3 > Na_3CO_3 > Ca CO_3 >MgCO_3}\)
Therefore \({MgCO_3}\) releases \({CO_2}\) most easily
\({MgCO_3 ->[\Delta] MgO + CO_2}\)
