Ag^(+) + NH3 hArr [Ag(NH3)]^(+) , K1=3....

`Ag^(+) + NH_3 hArr [Ag(NH_3)]^(+) , K_1=3.5xx10^(-3)`
, `[Ag(NH_3)]^(+) + NH_3 hArr [Ag(NH_3)_2]^(+) , K_2=1.7xx10^(-3)` . Calculate the formation constant of `[Ag(NH_3)_2]^+`. What is the instability constant ?

Text Solution

Verified by Experts

Overall formation constant is the product of successive formation constants,`K_(c)=K_(1)xxK_(2)`.
Formation constant of `[Ag(NH_(3))_(2)]^(+)=3.5xx10^(-3)xx1.7xx10^(-3)=5.95xx10^(-6)`.
