In equalitative analysis, cations of graph II as well as group IV both are precipitated in the form of sulphides. Due to low value of K_(sp) of group II sulphides, group reagent is H_(2)S in the presence of dil. HC1 , and due to high value of K_(sp) of group IV sulphides, group reagent is H_(2)S in the presence of NH_(4)OH and NH_(4)C1 . In a solution containing 0.1M each of Sn^(2+), Cd^(2+) , and Ni^(2+) ions, H_(2)S gas is passed. K_(sp) of SnS = 8 xx 10^(-29), K_(sp) of CdS = 15 10^(-28), K_(sp) of NiS - 3 xx 10^(-21), K_(1) of H_(2)S = 1 xx 10^(-7), K_(2) of H_(2)S = 1 xx 10^(-14) If H_(2)S is passed into the above mixture in the presence of HC1 , which ion will be precipitated first?

(x)/(20)M concentration of H^(+) ion must be maintained in a saturate H_(2)S(0.1M) to precipitates CdS but not ZnZ, if [Cd^(2+)]=[Zn^(2+)]=0.1M initially. K_(sp)(CdS)=8xx10^(-27), K_(sp)(ZnS)=1xx10^(-21)K_(a)(H_(2)S)=1xx10^(-21)ZnS will not precipitate at concentration of H^(+) greater than (x)/(20)M . The value of x is .
