Question

Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water. nickel(II) cyanide silver hydroxide

Answer 1

`Ksp=[Ni^(2+)][CN^-]^2\\\\Ksp=[Ag^+][OH^-]`

Step-by-step explanation:

Hello there!.

In this case, for this equilibrium problem, it turns out firstly necessary to write the chemical equations for the solubilization of both nickel (II) cyanide and silver hydroxide as shown below:

`Ni(CN)_2(s)\rightarrow Ni^(2+)(aq)+2CN^-\\\\AgOH(s)\rightarrow Ag^+(aq)+OH^-`

Thus, by means of the law of mass action we set up these equilibrium expressions as shown below:

`Ksp=[Ni^(2+)][CN^-]^2\\\\Ksp=[Ag^+][OH^-]`

Best regards!
