Sodium Citrate Dihydrate → 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, cerium(3+) salt (1:1)

Participants

Reaction Steps

Cerium (III) citrate was prepared as follows—3.726 grams of cerium (III) chloride heptahydrate in 30 milliliters of water was added to 2.941 grams of sodium citrate dihydrate in 30 milliliters of water. A white precipitate formed and was centrifuged out at 3500 RPM for 5 minutes. The supernatant was poured off. The precipitate was then washed 5 times (to remove dissolved sodium chloride) with 30 milliliters of water by (for each wash) a) addition of water to the precipitate, b) vortex mixing for 2 minutes, and c) centrifugation at 3500 RPM for 5 minutes. The precipitate was then washed in a similar manner 3 times (to remove residual water) with 30 milliliters of methanol (for each wash).
