Zn^(+2) + 2NH(3) hArr [Zn(NH(3))(2)]^(+2...

`Zn^(+2) + 2NH_(3) hArr [Zn(NH_(3))_(2)]^(+2), K_(1) = 2xx10^(-3)`
`[Zn(NH_(3))_(2)]^(+2) + 2NH_(3) hArr [Zn(NH_(3))_(4)]^(2+), K_(2) = 1.5xx10^(-3)`
Find out the instability constant?

Text Solution

Verified by Experts

`K_(C) = K_(1).K_(2) = 2xx10^(-3)xx1.5xx10^(-3) = 3xx10^(-6)`
Instability constant is inverse of stability constant
`(1)/(K_(C)) = (1)/(3xx10^(-6)) = 3.3xx10^(5)`
