Students at Gonzaga University were attempting to make barium phosphate by precipitation when mixing solutions of barium chlorid
e and trisodium phosphate:17 BaCl2(aq) + Na3PO4(aq) â Ba3(PO4)2 + 6NaCl(aq)
In one case, 0.504 g of BaCl, and 0.611 g of Na PO, were each dissolved separately in -50 mL H,O in beakers. The Na, PO, solution was poured into the BaCl, solution with mixing and the resulting suspension of white powder was digested at 80°C for 30 min to give 0.756 g of white solid after filtration, washing, and air drying.
