Solution

The correct option is C Assertion is correct but Reason is incorrect
${C u C O}_{3} ⟶ C U O + {C O}_{2}$
$A$ $B$ $C$
$C U O + H_{2} ⟶ C U + H_{2} O$
$C U O + 2 H C l + K_{4} [{F e C N}_{6}] \to {C U}_{2} [F e {(C N)}_{6}] + H_{2} O + K C l$
$(E)$ $(F)$
${C O}_{2} + l i m e w a t e r \to m e t a l l y e x c e s s ⟶ {C O}_{2} {C a ({H C O}_{3})}_{2}$
Assertion :
$F$ is bicarbonate.
Reason :
All metal bicarbonates are water soluble except barium bi-carbonate.
