1.	The reagents like AgNO_(3),K_(4)[Fe(CN)_(6)],KCNS,KI,K_(2)CrO_(4) Nessler's ect, find extenstive and very important applicasionin quentitative analysis because these resgents form different type of produce with different cation for axample KI form yellow precipitate with Pb^(2+) but at form red iprecipitate with Hg^(2+) , Hence these reagents are widelyused in the quantitative amalysis of morgenic salts Which of the following is not currectly matched ?
Answer» `Ag^(o+) + S_(2)O_(3)^(2-) rarr `WHITE ppt. `Pb_((aq))^(2+)2CI_((aq))^(Θ) rarr` Black perecipitate `Bil_(3)("Black preciplate") + H_(2)O(1) overset(Delta)rarr` orange turbidity `Ca_((aq))^(2+) + K_(4)[Fe(CN)_(6)]_(aq) rarr` white precipitate Solution :(a)`Ag^(o+)+S_(2)O_(3)^(2-) rarr Ag_(2)S_(2)O_(3)` (white ppt) B. `Pb_((aq))^(2+)+ 2CI_ (aq)^(Theta) rarr PbCI_(2)` c. `BiI_(1) darr ("black precipitate") + H_(2)O overset(Delta) to underset(("Orange"))(BIOI darr)` d. `Ca^(2+) + 2K^(o+) + [Fe(CN)_(6)]^(4-) rarr underset(("White"))(K_(2)Ca[Fe(CN)_(6)) darr)`
