Question

Identify (A) to (G) in the following scheme and name the process.
`CaCO_(3) overset(Delta) to (A) + (B) gas , (A) + H_(2)O rarr (C )`
`(C )+B rarr CaCO_(3) + H_(2)O (D) +(C ) overset(Delta) to (E ) gas`
`(E ) + H_(2)O + (B) rarr (F) , NaCI + (F) rarr (G) + (D)`
`(G) overset(Delta) to Na_(3)CO_(3) + H_(2)O + (B)`

Answer 1

Sheme repersent the solvay process of manufacture of `Na_(2)CO_(3)`
`CaCO_(3)overset(Delta)rarr underset((A))(CaO)+underset((B)(CO_(2)(g))`
`underset((A))(CaO +) H_(2)O rarr underset((C))(Ca(OH)_(2))`
`Ca(OH)_(2) +CO_(2) rarr CaCO_(3) +H_(2)O`
`underset((D))(NH_(4)CI) + underset((C))(Ca(OH)_(2)) overset(Delta)rarr underset((E))(NH_(3)darr)`
`underset((E))(NH_(3)) + H_(2)O + underset((B))(CO_(2)) rarr underset((F))(NH_(4)HCO_(3))`
`NaCI + underset((F))(NH_(4)HCO_(3)) rarr underset((G))(NaHCO_(3)) + underset((D))(NH_(4)CI)`
`2NaHCO_(3) overset(Delta)rarr Na_(2)CO_(3) + H_(2)O +underset((B))(CO_(2))`
