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 ? |

Answer» Solution :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`. |
