1.	if 500 mL of 0.4 M AgNO_3 is mixed with 500 mL of 2M NH_3 solution the what is the concentration ofAg (NH_3 ) ^(+)in solution?[Given :K_(f_1) [Ag (NH_3) ^(+)] =10 ^(3) , K _(f_2)[Ag (NH_3)_2^(+) ]= 10^(4) ]
Answer» ` 3.33 xx 10^(-7)M` ` 3. 33 xx 10^(-5 )M` ` 3 xx 10^(-4) M` ` 10 ^(-7) ` Solution :After MIXING ,` [AG^(+) ] =0.2 M, [NH_3]=1M` ` K_(f_1) xx K_(f_2)=10 ^(7) ` Due to high `K_f` value , most of the `Ag^(+) ` converted into` [Ag(NH_3)_2]^(+) ` `{:( Ag^(+) +,2NH_3 hArr, [Ag(NH_3)_2 ]^(+)), (0.2 M, 1M, 0), (, 1-04-0.6M, 0.2M):} ` ` {:([Ag(NH_3)_2]^(+) ,hArr ,Ag(NH_3)^(+), +NH_3) ,( 0.2 M, 0, 0.6M),( 0.2-y, y, 0.6+y),(~~0.2 , , ~~0.6):}` ` (1)/(10^(4) )= (yxx 0.6)/(0.2) =3y rArry =3.33 xx 10 ^(-5) M`
