Chapter 18, Problem 79(choose chapter or problem)
Aluminum compounds are soluble in acidic solution, where aluminum(III) exists as the complex ion Ag2CrO4 3Ag+4 F MgF21s2. - Cl- SO4 BaSO41s2; 2- 3 M Na2CO3 Ca1OH221aq2 Ca1OH221aq2 CaCl21aq2? 3Ca1OH221aq24, CO21s2, Na2HPO41aq2, CaCl21aq2 Kspa NaCH3COO? = 3 * 107. 0.100 M CH3COOH - 0.500 M Ca2+1aq2 + HCO3 -1aq2 + H2O1l2 CaCO31s2 + H3O+1aq2 pH = 5.6; pH = 4.20. which is generally represented simply as They are also soluble in basic solutions, where the aluminum(III) is present as the complex ion At certain intermediate pH values, the concentration of aluminum(III) that can exist in solution is at a minimum. Thus, a plot of the total concentration of aluminum(III) in solution as a function of pH yields a U-shaped curve. Demonstrate that this is the case with a few calculations.
