A 0.5086 g solid sample containing a mixture of LaCl, (molar mass =245.26 g/mol) and Ce(NO,), (molar mass =326.13 g/mol) was dissolved in water. The solution was titrated with KIO,, producing the precipitates La(IO,), andCe(IO,)3. For the complete titration of both La³+ and Ce+, 44.42 mL of 0.1294 M KIO, was required.

68. Aluminum ion may be precipitated from aqueous solution by addition of hydroxide ion, forming Al(OH)3. A large excess of hydroxide ion must not be added, however, because the precipitate of Al(OH)3 will redissolve as a soluble compound containing aluminum ions and hydroxide ions begins to form. How many grains of solid NaOH should be added to 10.0 mL of 0.250 M A1Cl3 to just precipitate all the aluminum?
