Question

Among the following the least thermally stable is (A)  K2CO3  (B)  Na2CO3  (C)  BaCO3  (D)  Li2CO3

Tardigrade Admin · Accepted Answer

Thermal stability of carbonates increases on moving down a group. Thus, lithium carbonate, Li2CO3 is least thermally stable. Li2CO3 xrightarrowΔ Li2O+CO2 uparrow

Q. Among the following the least thermally stable is

$K_{2} C O_{3}$

$N a_{2} C O_{3}$

$B a C O_{3}$

$L i_{2} C O_{3}$

Thermal stability of carbonates increases on moving down a group. Thus, lithium carbonate,
$L i_{2} C O_{3}$ is least thermally stable.
$L i_{2} C O_{3} Δ L i_{2} O + C O_{2} ↑$
