What is the oxidation number of phosphorus in PO4^3-?
Understand the Problem
The question is asking for the oxidation number of phosphorus in the phosphate ion (PO4^3-). To determine this, we need to consider the known oxidation states of the other elements in the ion and apply rules for calculating oxidation numbers.
Answer
+5
The final answer is +5
Answer for screen readers
The final answer is +5
More Information
Phosphorus can exhibit different oxidation states, but in the phosphate anion (PO4^3-), it is commonly +5 due to the overall charge balance and the fixed oxidation state of oxygen.
Tips
A common mistake is not taking the overall charge of the ion into account when calculating the oxidation number.
