Assertion: When a solution of Na(2)ZnO(2...

Assertion: When a solution of `Na_(2)ZnO_(2)` is acidified with dilute HCl and treated with `H_(2)S,` a precipitate of ZnS is formed.
Reason: `Na_(2)ZnO_(2)` is decomposed by HCl to give `Zn^(2+)` ions.

A

If both (A) and (B) are correct and (R ) is the correct explqanation of (A)

B

If both (A) and (B) are correct but (R ) is not the correct explqanation of (A)

C

If (A) is correct ,but (R ) is incorrect

D

If (A) is incorrect ,but (R ) is correct

Text Solution

Verified by Experts

The correct Answer is:
d
Correct assertion (A)
`Na_(2)ZnO_(2) `+ `H_(2)S` rarr `overset(ZnS)underset((white))` + `2NaOH`
`NaZnO_(2)` is not acidified before passing `H_(2)S`

In qualitative analysis when H_(2)S is passed through an aqueous solution of salt acidified with dil. HCl, a black precipitate is obtained. On boiling the precipitate with dil. HNO_(3) , it forms a solution of blue colour. Addition of excess of aqueous solution of ammonia to this solution gives

(i) A white solid mixture of two salts containing a common cations in insoluble in water. It dissolves in dilute HCl producing some gases (with effervescence) that turn an acidified dichromate solution gren. After the gases are passed through the acidified dichromate solution, the emerging gas turns baryta water milky. (ii) On treatment with dilute HNO_(3) , the white solid gives a solution which does not directly give a precipitate with a BaCl_(2) solution but gives a white precipitate when warmed with H_(2)O_(2) and then treated with a BaCl_(2) solution. (iii) The solution of the mixture in dilute HCl, when treated with NH_(4)Cl,NH_(4)OH and an Na_(2)HPO_(4) solution, gives a white precipitate. Q. The white precipitate obtained in (ii) indicates the presence of a:
