Step-by-step solution
N H 3 + H 2 O + C O 2 → N H 4 H C O 3 N{H}_{3} + {H}_{2}O + C{O}_{2} \to N{H}_{4}HC{O}_{3} N H 3 + H 2 O + C O 2 → N H 4 H C O 3 N a + + C l − + N H 4 + + H C O 3 − → N a H C O 3 p p t . + N H 4 + + C l − Na^{+} + Cl^{-} + N{H}_{4}^{+} + HC{O}_{3}^{-} \to \mathop{NaHC{O}_{3}}_{ppt.} + N{H}_{4}^{+} + Cl^{-} N a + + C l − + N H 4 + + H C O 3 − → N a H C O 3 ppt . + N H 4 + + C l − 2 N a H C O 3 → Δ N a 2 C O 3 + C O 2 + H 2 O 2NaHC{O}_{3}\overset{\Delta}{→}N{a}_{2}C{O}_{3} + C{O}_{2} + {H}_{2}O 2 N a H C O 3 → Δ N a 2 C O 3 + C O 2 + H 2 O
