The aqueous solutions of the transition metal salts are acidic as a result of hydrolysis of their hydrated cations. The H2O in these hydrated cations can form different colors in the solution of colmplex ions by entering ligand exchange reaction with different ligands like CI, NH3 SO Cu2+ Fe2+ Cr3+ Ni2+ Co2+ Mn2+ Al3+ V3+ Sc3+ salts are separately a)Write down water-solubility / hydration reactions. b)Write down the hydrolysis reactions and explain the reason for the acidity according to the...

When salts dissolve in water, they dissociate into cations and anions which may undergo hydrolysis with water. In general, metal ions undergo hydrolysis to produce hydronium ion when the metal is a transition metal with a 2+ charge or higher, or a non-transition metal with a 3+ charge or higher. Which of the following salts should produce an acidic solution when dissolved in water? Select all that apply. There may be more than one correct answer. A. MgCl2 ...

1. When cobalt chloride is added to pure water, the Co2+ ions hydrate. The hydrated form then reacts with the Cl–ions to set up the equilibrium shown here: Co(H2O)62+ + 4Cl– CoCl42– + 6H2O (pink) (blue) Which statement describes the change that the system will undergo if potassium chloride is added? A) It should become more pink. B) Nothing will change. C) The silver ion will react with the CoCl42–. D) Water will be produced. E) It should become more blue.

conclusions: 1. If two salts release a different number of ions into solution when they dissolve, you can not compare ko values to determine which is more soluble. You must calculate the molar solubility values 2. If two salts release the same number of ions into solution, you do the exact same calculation of molar solubility. When this is true, you can compare Ksp values to determine which is more soluble. Do You Understand? 1. When you compare Mg3(PO4)2 (Ksp...
