Cu with the superscript 3+.
The ionic charge of Cu3(PO4)2 is +2. Each copper ion (Cu2+) has a charge of +2, while each phosphate ion (PO4) has a charge of -3, resulting in a net charge of +2 for the compound.
The formula for copper(I) phosphate is Cu3(PO4)2. In this compound, one copper ion with a +1 charge pairs with two phosphate ions, each carrying a -3 charge.
Cu3 is not a common or stable compound in chemistry. Copper typically forms compounds with other elements, such as CuO (copper oxide) or CuSO4 (copper sulfate), rather than existing as Cu3.
Na3PO4+CuBr2=Cu3(PO4)2+NaBr PO4 has a charge of -3 and Cu (in this equation as shown by CuBr2) has a charge of +2, when they combine you switch the chareges and add them on as subscripts to each other. Na and Br have the opposite charges, -1 and +1, so you don't have to add them to the equation.
The chemical symbol for cupric arsenate is Cu3(AsO4)2.
3Cu^2+(aq) + 2PO4^3-(aq)====>Cu3(PO4)2(s)
The chemical formula for copper (II) phosphate is Cu3(PO4)2.
Formula: Cu3(PO4)2
The chemical formula for copper (II) phosphate is Cu3(PO4)2.
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
Formula: Cu3(PO4)2
The most common one is Cu3(PO4)2. Another one is Cu(PO3)2.
