Cho sơ đồ:

$\Large {NaHCO}_{3} \stackrel{+{X}}{\longrightarrow} {Na}_{2} {SO}_{4} \stackrel{+{Y}}{\longrightarrow} {NaCl} \stackrel{+{Z}}{\longrightarrow} {NaNO}_{3} .$

$\Large {X}, {Y}, {Z}$ tương ứng là

• A.

  $\Large {NaHSO}_{4}, {BaCl}_{2}, {AgNO}_{3}$.

• B.

  $\Large {H}_{2} {SO}_{4}, {BaCl}_{2}, {HNO}_{3}$.

• C.

  $\Large {K}_{2} {SO}_{4}, {HCl}, {AgNO}_{3}$.

• D.

  $\Large \left({NH}_{4}\right)_{2} {SO}_{4}, {HCl}, {HNO}_{3}$.

$\Large {NaHCO}_{3}+{NaHSO}_{4}({X}) \rightarrow {Na}_{2} {SO}_{4}+{CO}_{2}+{H}_{2} {O}$

$\Large {Na}_{2} {SO}_{4}+{BaCl}_{2}({Y}) \rightarrow {BaSO}_{4}+2 {NaCl}$

$\Large {NaCl}+{AgNO}_{3}({Z}) \rightarrow {NaNO}_{3}+{AgCl}$
