Acidic aqueous solution contain CuSO4, ZnSO4,MgSO4,CdSO4 when react with H2S(. g .), Ions which is/are precepitated as metal sulphide.

Question

Acidic aqueous solution contain CuSO4, ZnSO4,MgSO4,CdSO4 when react with H2S(. g .), Ions which is/are precepitated as metal sulphide. (A) Cu+ 2,Cd+ 2 (B) only Cu+ 2 (C) Mg+ 2,Zn+ 2 (D) Cu+ 2,Zn+ 2,Cd+ 2

Tardigrade Admin · Accepted Answer

In acidic medium only group- II (.A>B.) metal can be precipitated on sulphide i.e., Cu+ 2 &Cd+ 2

Q. Acidic aqueous solution contain $C u S O_{4},$ $Z n S O_{4}, M g S O_{4}, C d S O_{4}$ when react with $H_{2} S_{(g)},$ Ions which is/are precepitated as metal sulphide.

$C u^{+ 2}, C d^{+ 2}$

only $C u^{+ 2}$

$M g^{+ 2}, Z n^{+ 2}$

$C u^{+ 2}, Z n^{+ 2}, C d^{+ 2}$

In acidic medium only group- $II$ $(A > B)$ metal can be precipitated on sulphide i.e., $C u^{+ 2} & C d^{+ 2}$

Q. Acidic aqueous solution contain CuSO4​, ZnSO4​,MgSO4​,CdSO4​ when react with H2​S(g)​, Ions which is/are precepitated as metal sulphide.

Cu+2,Cd+2

only Cu+2

Mg+2,Zn+2

Cu+2,Zn+2,Cd+2
