Guida verificata passo dopo passo1
Identify the overall charge of the ion, which is \(-3\) for \(\mathrm{PO_3^{3-}}\).
Recall that oxygen typically has an oxidation state of \(-2\) in most compounds.
Set up an equation where the oxidation state of phosphorus is \(x\), and the total oxidation states sum to the ion's charge: \(x + 3(-2) = -3\).
Simplify the equation: \(x - 6 = -3\).
Solve for \(x\) to find the oxidation state of phosphorus: \(x = -3 + 6\).
