`ZnCI_(2)+NaHCO_(3)overset("Heat")rarr (A)overset("Heat")rarr (B)+(C )+H_(2)O (B)+NaOH rarr (D)`
Identify the compound (D) present in the solution.

A

`ZnCO_(3)`

B

`Zn(OH)_(2)`

C

`ZnO`

D

`Na_(2)znO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`ZnCI_(2)+2NaHCO_(3)overset(Delta)rarr underset((A))Zn(HCO_(3))_(2)+2NaCI`
`underset((A))(Zn(HCO_(3))_(2))overset(Delta)rarr underset((B))(znCO_(3))+H_(2)O+underset((C ))(CO_(2)uarr)`
`underset((B))(ZnCO_(3)+2NaOH rarr underset((D))(Na_(2)ZnO_(2))+2H_(2)O`
