The Ca in a 200.0-mL sample of natural water was determined by precipitating the cation as CaC,O4 after the addition of oxalic acid (H2C204). C,0,2 (ag) + Ca²* (aq) → CaC,O4(s) The precipitate was filtered, washed & ignited in a crucible w/ an empty mass of 26.6002 g. CaC,O4(s) → CaO(s) + CO(g + CO2(g) (), The mass of the crucible plus CaO was 26.7134 g. Calculate the concentration of Ca (molarity) in the water sample.

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?

A 300.0-g sample of a solid is made up of a uniform mixture of NaNO3, MgCl2, and BaCl2. A 100.0-g sample of the mixture is dissolved in water and treated with an excess of KOH. The precipitate from the reaction has a mass of 13.47 g. The remaining 200.0-g sample is also dissolved in water and treated with an aqueous solution of AgNO3. The resulting precipitate has a mass of 195.8 g. What are the masses of NaNO3, MgCl2, and BaCl2 in the 300.0-g sample?
