Comment True (T) or False (F) for the following statements:
(P) Same gas comes out when `Na_(2)S` is treated with dil `HCI` and `Na_(2)SO_(3)` is treated with `(Zn+` dil `H_(2)SO_(4))`.
(Q) Same obervation when acidified nitrite solution is treated with urea or thiourea followed by addition of `FeCI_(3)` solution.
(R) Same observation when nitrite solution or acetate solution is treated with dil. `H_(2)SO_(4)` solution.
(S) With `CaCI_(2)` and `BaCI_(2)` both acetate and formate do not react.

Options

A. FTTF
B. TFTT
C. TFFT
D. FTTT

Answer

A

Explanation

(P) `SO_(3)^(2-) overset(Zn+dil. H_(2)SO_(4))rarr S^(2-) overset(HCI)rarr H_(2)S uarr`
(S) Both `CaCI_(2)` and `BaCI_(2)` reacts with `AcO^(-)` and `HCOO^(-)` but no change in colour.
