Vedclass · Answer

(A) Compound $(A)$ is $NaCl$,which is a white crystalline solid having a rock salt crystal structure.$(B)$ is $Cl_2$,a pungent-smelling,greenish-yellow gas produced by the reaction of $NaCl$ with conc. $H_2SO_4$ and $MnO_2$.The reaction is: $2NaCl + 2H_2SO_4 + MnO_2 \rightarrow Na_2SO_4 + MnSO_4 + 2H_2O + Cl_2$.Compound $(A)$ reacts with $AgNO_3$ to form a white precipitate of $(C)$,which is $AgCl$.The reaction is: $AgNO_3 + NaCl \rightarrow NaNO_3 + AgCl(s)$ (white ppt).Therefore,$(A) = NaCl$,$(B) = Cl_2$,and $(C) = AgCl$.
