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_1xxK_2`.
Formation constant of `[Ag(NH_3)_2]^(+) =3.5xx10^(-3)xx1.7xx10^(-3)=5.95xx10^(-6)`
Instability constant is the inverse of the stability constant, `1/K_c=1/(5.95xx10^(-6))=1.7xx10^7`.
