V+4 PO4-3 <--- these are the ions and their charges V+4 V+4 V+4 PO4-3 PO4-3 PO4-3 PO4-3 <--- the charges have to add up to zero, so three +4 vanadium ions cancels out four -3 phosphate ions V3(PO4)4 <--- simplify
Al+3+ PO4^-3 AlPO4
a phosphate ion is PO43-
Trisodium Phosphate = Na3PO4 It contains Na+ and PO4-3 ions.
germanium has an oxidation number of +4, phosphate is PO4 has an oxidation number -3. Ge3(PO4)4
PO4
(Hg2)3(PO4)2
The chemical formula of barium phosphate is Ba3(PO4)2.
Mo3(PO4)4
formula for Copper (I) is Cu- and the formula for Phosphate is (PO4)3- the two have to have a net charge of zero, but (Cu)-(PO4)3- is uneven +1+-3=-2 so adding 2 more Copper (I) to the compound the formula Cu3PO4 ends up as leaving the net charge to be 0 = +3 + -3
V+4 PO4-3 <--- these are the ions and their charges V+4 V+4 V+4 PO4-3 PO4-3 PO4-3 PO4-3 <--- the charges have to add up to zero, so three +4 vanadium ions cancels out four -3 phosphate ions V3(PO4)4 <--- simplify
Formula: (Hg2)3(PO4)2
Cu3PO4
T he correct formula for iron(III) phosphate is Fe3(PO4)2.
Al+3+ PO4^-3 AlPO4
Calcium phosphate = Ca2+ PO4-3 = Ca3(PO4)2
a phosphate ion is PO43-
