You prepare a standard NaOH solution for the laboratory, using potassium hydrogen phthalate (KHC₈H₄O₄, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. It took 31.55 mL of the NaOH solution to titrate (react exactly with) 0.750 g KHP. You then use the standard base solution to determine the amount of ascorbic acid in a 500.0 mg tablet of vitamin C. Ascorbic acid (HC₆H₇O₆, molar mass 176.12 g/mol) also has one acidic hydrogen, and is usually mixed with some filler in preparing the tablets. It requires 17.54 mL of the NaOH to titrate (react exactly with) the ascorbic acid found in one 500.0 mg tablet. What is the percent vitamin C by mass in the tablet?

The solubility product of aluminum hydroxide (Al(OH)3) is 1.9x10–33. Derive an equation for the concentration of Al3+ in water as a function of pH if the water is saturated with Al(OH)3. If the concentration of Al3+ in water cannot exceed 10 micromolar (because all the aluminum has dissolved), at what pH would you expect the product of the Al3+ concentration and the PO43− concentration to be a maximum? Explain your reasoning.
