There are two possibillities:Monohydrogen Phosphate ion: HPO42-Dihydrogen Phosphate ion: H2PO4-
The formula for hydrogen phosphate ion is: H2PO4−
The phosphate ion is PO43-
The chemical formula for dihydrogen phosphate ion is H2PO4-
Phosphate is an ion with the formula PO43-. The 3- indicates the charge on the ion. This ion consists of the pnonmetals phosphorus and oxygen. The negative ion must be paired with a positive ion to form an actual substance. That ion is usually a metal ion. So phosphate itself is not a metal but many phosphate compounds contain metals.
The phosphate ion PO43-
a phosphate ion is PO43-
There are two possibillities:Monohydrogen Phosphate ion: HPO42-Dihydrogen Phosphate ion: H2PO4-
An anion. For which element, I am not sure. Let someone else answer that.
The phosphate ion is (PO4)3-.
The formula for hydrogen phosphate ion is: H2PO4−
The phosphate ion is PO43-
The chemical formula for dihydrogen phosphate ion is H2PO4-
Phosphate is an ion with the formula PO43-. The 3- indicates the charge on the ion. This ion consists of the pnonmetals phosphorus and oxygen. The negative ion must be paired with a positive ion to form an actual substance. That ion is usually a metal ion. So phosphate itself is not a metal but many phosphate compounds contain metals.
The phosphate ion is (PO4)3-. Hence, Calcium phosphate is Ca3(PO4)2 as the Calcium ion is Ca2+)
sodium phosphate Na3PO4
Phosphate ion is: (PO4)3-.
