Homework Answers
Question 1.
NiCO3(s) + 4CN-(aq) <----> [Ni(CN)4]2-(aq) + CO32-(aq)
K = Ksp * Kf = 1.42*10-7 * 2*1031 = 2.84*1024
Explanation: The above equation can be obtained by the adding the two equilibria mentioned below.
NiCO3(s) <----> Ni2+(aq) + CO32-(aq); Ksp = 1.42*10-7 ---- Equilibrium 1
Ni2+(aq) + 4CN-(aq) <----> [Ni(CN)4]2-(aq); Kf = 2*1031---- Equilibrium 2
