Sodium Tripolyphosphate (STPP)
STPP los yog sodium triphosphate yog ib qho inorganic compound nrog formula Na5P3O10.STPP,Sodium Tripolyphosphateyog sodium ntsev ntawm polyphosphate penta-anion, uas yog conjugate puag ntawm triphosphoric acid.Sodium tripolyphosphate yog tsim los ntawm cua sov ib stoichiometric sib tov ntawm disodium phosphate, Na2HPO4, thiab monosodium phosphate, NaH2PO4, nyob rau hauv ua tib zoo tswj tej yam kev mob.Sodium tripolyphosphate stpp
