Oxalate ion will interfere with the Group D tests after we make the solution acidic. Also, ammonium ion may prevent the precipitation of Group Dcations as hydroxides in sodium hydroxide solution. Thus, must treat the supernatant liquid left after we have precipitated calcium oxalate, in order to destroy any remaining Oxalate or ammonium ions prior to further analysis. To accomplish this, we transfer the solution to a crucible, add concentrated nitric acid and heat the mixture to dryness in a...

NONTON Aluminum ions may be precipitated from aqueous solution by the 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 begin to form. How many grams of solid NaOH should be added to 10.0 mL of 0.131 M AICI: to just precipitate all the aluminum?
