Find the number of yellow colour sulphide(s) in the following :-

CdS, Sb₂S₃ , As₂S₃ , As₂S₅ , SnS₂ , ZnS , PbS

Answer:

Solution:

In salt analysis, sulfides of Group II cations show characteristic colors.

CdS, As₂S₃, As₂S₅, and SnS₂ form yellow-colored sulfide precipitates.

Sb₂S₃ is orange, ZnS is white, and PbS is black in color.

Hence, the total number of yellow sulfides is 4.
