Cho sơ đồ phản ứng: $\large NaCl \to \left( X \right)\to NaHC{{O}_{3}}

Cho sơ đồ phản ứng: $\large NaCl \to \left( X \right)\to NaHC{{O}_{3}}\to \left( Y \right)\to NaN{{O}_{3}}$. X và Y có thể là

• A. $\large NaOH\,v\grave{a}\,NaClO$.
• B. $\large N{{a}_{2}}C{{O}_{3}}~v\grave{a}\,NaClO$. 
• C. $\large NaCl{{O}_{3}}~v\grave{a}\,N{{a}_{2}}C{{O}_{3}}$.
• D. $\large NaOH\,v\grave{a}\,N{{a}_{2}}C{{O}_{3}}$.

$\large 2NaCl+2{{H}_{2}}O\xrightarrow{đpd\text{d}\,\,\text{m/n}}2NaOH+{{H}_{2}}+C{{l}_{2}}$

$\large NaOH+C{{O}_{2\,dư}}\to NaHC{{O}_{3}}$

$\large 2NaHC{{O}_{3}}\xrightarrow{{{t}^{o}}}N{{a}_{2}}C{{O}_{3}}+C{{O}_{2}}+{{H}_{2}}O$

$\large N{{a}_{2}}C{{O}_{3}}+Ba{{(N{{O}_{3}})}_{2}}\to BaC{{\text{O}}_{3}}+2NaN{{\text{O}}_{3}}$
