Question

give the correct chemical name for the following chemical formula: fepo₄ when is fe³+

Explanation:

Step1: Identify the cation

The cation is \(Fe^{3+}\). In naming ionic compounds with transition metals, we use Roman numerals to indicate the charge. Here, the charge is \(+3\), so it's "iron(III)".

Step2: Identify the anion

The anion is \(PO_{4}^{3 -}\). The name of the \(PO_{4}^{3 -}\) ion is phosphate.

Step3: Combine cation and anion names

Combine the names of the cation and anion. So, \(FePO_{4}\) (with \(Fe^{3+}\)) is named iron(III) phosphate.

Answer:

Iron(III) phosphate
