反応手順

To sixty grams of bright casing solution contained in a beaker and given continuous agitation with a magnetic stir bar, there were added 1.34 grams of Ca(OH)2 powder, 15 grams of CaCO3 powder, and 22.0 grams of citric acid dissolved in 60 ml of water. Upon completion of effervescence, the mixture was filtered through a Whatman grade 54 filter paper. The resultant clear solution had a pH of 3.47 and a solids content of about 19.3%. If allowed to stand quiescent for 15 hours, it formed a precipitate of calcium citrate, Ca3 (C6H5O7)2.4H2O.
