The negative ion for iron(III) phosphate is PO4^3- called phosphate ion.
The charge on a phosphate ion is -3.
The formula for hydrogen phosphate ion is: H2PO4−
The phosphate ion is (PO4)3-.
a phosphate ion is PO43-
The chemical formula for dihydrogen phosphate ion is H2PO4-
The charge of a phosphate ion (PO4) is -3.
The phosphate ion is (PO4)3-. Hence, Calcium phosphate is Ca3(PO4)2 as the Calcium ion is Ca2+)
The equivalent weight of calcium phosphate is calculated by dividing the molar mass of calcium phosphate by the valency factor of the phosphate ion. Since calcium phosphate is a salt with the formula Ca₃(PO₄)₂, its molar mass is calculated by adding the molar masses of calcium and phosphorus (since there are three calcium ions and two phosphate ions in the formula). The valency factor of phosphate ion is 2 since it can donate or accept 2 electrons.
A phosphorus ion is called a phosphate ion, which has a charge of -3.
monohydrogen phosphate
An anion. For which element, I am not sure. Let someone else answer that.
