What is the oxidation number of PO4?
Understand the Problem
The question is asking for the oxidation number of the phosphate ion (PO4). This involves understanding how oxidation states are assigned to elements within a compound.
Answer
+5
The final answer is +5
Answer for screen readers
The final answer is +5
More Information
In the phosphate ion (PO4³⁻), each oxygen has an oxidation number of -2. Since the total charge of PO4³⁻ is -3, the oxidation number of phosphorus must be +5 to balance the overall charge.
Tips
A common mistake is omitting the overall charge of the ion when calculating oxidation numbers, which can lead to incorrect results.
