Identify(A) based on following facts :
a. `A` reduces `HgCl_(2)` solution to white ppt. charging to grey .
b. (A) turns ` FeCl_3` yellow colured solution to green .
c. (A) give white ppt, with `NaOH` soluble in excess of `NaOH` .
d. (A) gives yellow dirty ppt. on passing `H_2S` gas , soluble in yellow ammonium sulphjde (YAS).
e. (A) gives chromyl chloride test .

Text Solution

Verified by Experts

(A) Gives yellow dirty ppt soluble in `YAS`
`rArr` (A) has `Sn^(2+)`
(A) gives chromyl chloride test (of `CI^(Theta))`
`rArr` (A) has `CI^(Theta)`
`(A)` is `SaCI_(2)`
Explanation:
a. `SnCI_(2)+2HgCI_(2) rarr underset("white")(Hg_(2)CI_(2)darr)+SnCI_(4)`
`SnCI_(2)+Hg_(2)CI_(2) rarr underset("Grey")(2Hg)+snCI_(4)`
b. `underset("Yellow")(2FeCI_(3)) +SnCI_(2) rarr underset("Green")(2FeCI_(2))+SnCI_(4)`
e. `SnCI_(2) +2NaOH rarr underset("white")(Sn(OH)_(2)darr)+2NaCI`
`Sn(OH)_(2) +2NaOH rarr underset(("sodium stannite"))underset("Soluble")(Na_(2)SnO_(2)+)2H_(2)O`
d. `SnCI_(2)+H_(2)S rarr 2HCI +underset("Yellow")(SnSdar)`
`SnS+underset(YAS)((NH_(4))_(2))S_(2) rarr underset("Soluble")((NH_(4))_(2)SnS_(3))`
