  • Dicalcium phosphate — Wikipedia Republished // WIKI 2

    Di­cal­cium phosphate is the cal­cium phos­phate with the for­mula CaHPO 4 and its di­hy­drate. The "di" pre­fix in the com­mon name arises be­cause the for­ma­tion of the HPO 42– anion in­volves the re­moval of two pro­tons from phos­phoric acid, H 3 PO 4.
