Question

For each of the salts on the left, match the salts on the right that can be compared directly. using K_sp values, to estimate solubility (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e. g, ABC) manganese(II) sulfide nickel (II) cyanide A. Zn(OH)_2 B. Fe_2 S_3 C. FeS D. Mn(OH)_2 Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water manganese(II) sulfide K_sp = nickel(II) cyanide K_sp =

Explanation / Answer

For each of the salts on the left, match the salts on the right that can be compared directly, using Kspvalues, to estimate solubilities.

For ; manganese sulfide MnS    C. FeS

Nichel (II) cyanide Ni(CN)2   A. Zn(OH)2

                                      D. Mn(OH)2

manganese sulfide MnS:

Ksp = [Mn+2][S-2]
Solubility of MnS = S mol/L
[Mn+2] = S mol/L
[S-2] = S mol/L

Ksp = [Mn+2][S-2] = S*S

Ksp =S^2

Nichel (II) cyanide Ni(CN)2 :

Ksp = [Ni+2][CN-]^2
Solubility of Ni(CN)2 = S mol/L
[Ni+2] = S mol/L
[CN-] =2 S mol/L

Ksp = Ni(CN)2 = S*(2S)2

Ksp =4S^3
