Which of the following raw materials is used in the manufacture of `Na_(2)CO_(3)` by Solvay process?

A

`Ca(OH)_(2),NH_(3),CO_(2)`

B

`Ca(Cl)_(2),NH_(3),CO_(2)`

C

`NaOH,NH_(3),CO_(2)`

D

`NaCl,NH_(3),CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
(d)
Solvay's process for the manufacture of `Na_(2)CO_(3)` is as follows,
`NH_(3) + H_(2)0 + CO_(2) rarr NH_(4)HCO_(3)`
`NH_(4)HCO_(3) + NaCl + CO_(2) rarr NaHCO_(3) + NH_(4)Cl `
`2NaHCO_(3) overset("Roasting") Na_(2)CO_(3) + H_(2)O + CO_(2)`
Hence, `NH_(3),CO_(2) and NaCl` are used as raw materials.
