Answer: Equilibrium constant for this reaction is 
.
Explanation:
Chemical reaction equation for the formation of nickel cyanide complex is as follows.
 + 2OH^{-}(aq)](https://tex.z-dn.net/?f=Ni%28OH%29_%7B2%7D%28s%29%20%2B%204CN%5E%7B-%7D%28aq%29%20%5Crightleftharpoons%20%5BNi%28CN%29_%7B4%7D%5E%7B2-%7D%5D%28aq%29%20%2B%202OH%5E%7B-%7D%28aq%29)
We know that,
K = 
We are given that, 
and, 
Hence, we will calculate the value of K as follows.
K =
K = 
=
Thus, we can conclude that equilibrium constant for this reaction is .

Explanation:
A reaction between colorless substances can produce a colored precipitate by formation of new ionic compound.
<h3>What is an ionic compound?</h3>
An ionic compound is a compound that is made up of two elements, one metal and the other non metal, which are held together by an ionic bonding.
When reaction occurs between two colourless substances, colored precipitate results by formation of new ionic compound.
