Vedclass · Answer

(B) The reaction sequence is characteristic of sodium bicarbonate $(NaHCO_3)$:$1$. $2NaHCO_3 \xrightarrow{\Delta} Na_2CO_3 + H_2O + CO_2(g)$. Here $A = NaHCO_3$,$B = Na_2CO_3$,and $C = CO_2$.$2$. $CO_2 + Ca(OH)_2 \rightarrow CaCO_3(milky) + H_2O$. Here $D = CaCO_3$.$3$. $CaCO_3 + H_2O + CO_2 \rightarrow Ca(HCO_3)_2$. Here $E = Ca(HCO_3)_2$.Evaluating the options:- $A$ is $NaHCO_3$ (Correct).- $B$ $(Na_2CO_3)$ is a metal carbonate soluble in water (Incorrect,as $Na_2CO_3$ is soluble).- $A$ $(NaHCO_3)$ is amphoteric,but $E$ $(Ca(HCO_3)_2)$ is also amphoteric (Correct).- $D$ is $CaCO_3$ (Correct).Since $Na_2CO_3$ is soluble in water,statement $B$ is incorrect.

$A$ $\xrightarrow{\Delta} B + C_{(gas)}$ $\xrightarrow{Ca(OH)_2} D_{(milky)} + H_2O$ $\xrightarrow{C_{(gas)}} E$. Then the incorrect statement is:
