General Chemistry
What will happen to the solubility of Fe(OH)3 when KCN(aq) is added to the solution? Provide the balanced net ionic equation for the dissolution process. [Hint: Refer to complex ions formations]
What is the molar solubility of AgCl in pure water and in 0.20 M Na2S2O3 solution? Use the following values: Ksp AgCl = 1.8×10–10 and Kf [Ag(S2O3)2]3– = 4.7×1013.
Determine the equilibrium constant for the reaction with their Ksp and Kf values
CuS (s) + 6 CN- (aq) ⇌ Cu(CN)42- (aq) + S2- (aq) (Ksp = 2x10-47, Kf = 1x1025)
Determine the concentration of Ni2+ that remains when a solution of 1.3 × 10-3 M Ni(NO3)2 and 0.173 M NH3 reaches equilibrium.
Kf (Ni(NH3)62+) = 1.2 × 109
Which one of following statements about copper(I) iodide (CuI, Ksp = 1.10×10–12) and Copper(II) carbonate (CuCO3, Ksp = 1.40×10–10) is incorrect.
