Question

For a particular complex, the dissociation equilibrium constant is given as 2.3 x 10^-9. What will be the overall stability constant for this complex?

(a) 4.35 x 10^-10

(b) 4.35 x 10^10

(c) 4.35 x 10^-8

(d) 4.35 x 10^8

I got this question during a job interview.

My enquiry is from Stability of Coordination Compounds topic in section Coordination Compounds of Chemistry – Class 12

Answer 1

Right choice is (d) 4.35 x 10^8

For explanation I would say: Formation constant = 1/(dissociation constant)

\(\Rightarrow\)β = 1/(2.3 x 10^-9)

\(\Rightarrow\)β = 4.35 x 10^8
