The simultaneous solubility of Ag CN (K_(f)=2.5 xx 10^(-16)) and AgCl

1.	The simultaneous solubility of Ag CN (K_(f)=2.5 xx 10^(-16)) and AgCl (Ksp =1.6 xx 10^(-10 ) )in 1. 0M NH_3 (aq)are respectively :[Given ,K_f [Ag(NH_3)_2^(+) ]= 10^(7) ]
Answer» Solution :`AGL hArr Ag^(+) I^(-),Ksp` ` (Ag^(+) +2CN^(-)hArr [Ag(CN)_2]^(-),K_f)/( underset( 1-2s) (Agl)+2CN^(-)hArr [Ag(CN)_2]^(-)+I^(-),K =KspK_f) ` ` ((s)/(1-2s) )^(2)=Ksp, K_f =1.2 XX 10^(-17)xx 7.1 xx 10 ^(19) ` ` rArr (s)/( 1-2s)=sqrt(8.52 xx 10 ^(2)) =29` ` 59S =29 rArr S =0.49 rArr S = 4.9 xx 10 ^(-1) `
