Is lead phosphate soluble

Witryna17 kwi 2024 · The presence of equimolar levels of oxalate and phosphate resulted in up to 250-fold increase in Pb solubility at acidic pH and about a 4-fold increase at pH 7.0, due to the strong suppression of Pb phosphate precipitation by oxalate and formation of soluble Pb-oxalate complexes. Witryna26 cze 2016 · You know that you're dealing with a solution of lead (II) phosphate, an insoluble ionic compound that does not dissociate completely when dissolved in water. The first thing to do here is write the equilibrium reaction that describes the partial dissociation of the salt. Pb3(PO4)2(s) ⇌ 3Pb2+ (aq) + 2PO3− 4(aq)
