Chemistry - Salt Analysis Question with Solution | TestHub

Here statement in option B is incorrect as when$\mathrm{C}{\mathrm{O}}_2$is passed in lime-water, it becomes milky due to the formation of$\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{O}}_3$but excess of$\mathrm{C}{\mathrm{O}}_2$leads to the formation of clear solution, due to the formation of soluble$\mathrm{C}\mathrm{a}(\mathrm{H}\mathrm{C}{\mathrm{O}}_3{)}_2$.

A.$\mathrm{M}\mathrm{g}+\mathrm{C}{\mathrm{O}}_2\to 2\mathrm{M}\mathrm{g}\mathrm{O}+\mathrm{C}$
and$2\mathrm{M}\mathrm{g}+\mathrm{S}{\mathrm{O}}_2\to 2\mathrm{M}\mathrm{g}\mathrm{O}+\mathrm{S}$

D. Inter-atomic forces (or metallic bonding) in alkaline-earth metals are stronger than in alkali metals.
