aaquairon(III) ions, Fe(H,0) 3+, form. Fe(H,0)+ ions 4. When Fe(NO3)3 is dissolved in water, hexaaquairon(III) ions,...
What happens when V(NO3)3 is dissolved in water? The water molecules surround the following ions. vanadium(III) cation and nitrate anion vanadium(III) anion and nitrate cation vanadium(I) cation and nitrate anion vanadium(I) anion and nitrate cation These ions are separate from one another and each is surrounded by water molecules.
2nd part only the pH is correct. Metal ions in aqueous solutions are solvated, or hydrated, by water molecules. Typically this primary hydration sphere is composed of six water molecules. The hydrated metal ion acts as a weak acid, undergoing a stepwise hydrolysis in which it donates an Htion from its water ligands to the surrounding free water molecules. Shown is the hydrolysis of Al(H,0) (pKA = 4.85) in water. Al(H,0)(aq) + H20(1) - 1,0+ (aq) + Al( HO), OH...
1. When iron(II) ammonium sulfate is dissolved in water, it dissociates into its component ions. () → () + ( ) + ( ) 2. When oxalic acid is added, the iron (II) ions precipitate as iron(II) oxalate dihydrate. Fe2+ (aq) + (aq) + __H20 (1) ► ( ) + _ H(aq) 3. Next, potassium oxalate is added to the washed precipitate. Potassium oxalate dissociates into its ions in solution. At high oxalate concentrations, iron (II) oxalate combines with another...

When the transition metal materials are dissolved in the aqueous solution (e.g. Cu(NO3)2, Fe(NO3)3, K2CrO4, NiSO4), the solutions have color(such as blue, green and yellow color). Why do transition metal complexes make colored compounds in solution? Describe the relevant theory and reasons.
If 1.25 g Fe(NO3)3 is dissolved in enough water to make exactly 397 mL of solution, what is the molar concentration of nitrate ion?
2. Write chemical equations to explain the following observations: (a) When Cr(NO3)3 is dissolved in H20 the pH of the solution decreases thus becomes more acidic (Hint first consider forming the complex Cr(H20)63 and then consider what happen to this complex in water... I gave a similar example in the lectures) |(b) A precipitate of Al(OH)3 is redissolved with a basic solution containing lots of OH (6M KOH). (hint: what do you make here when Al(OH)3 combines with OH-? Check...
