Question

question 7

what is the oxidation state of phosphorus in the polyatomic anion \\(\text{po}_3^{3-}\\)?

if the oxidation state is positive just give the number (e.g. enter 1 for +1)

if the oxidation state is negative give the negative number (e.g. enter -1 for -1)

if the oxidation state is zero, enter 0

Explanation:

Set up the oxidation state equation

Using the Oxidation State Rules and Oxidation Number Calculation knowledge points

$$ \text{Let } x \text{ be the oxidation state of phosphorus (P) in } \text{PO}_3^{3-}. $$

$$ x + 3(-2) = -3 $$

Solve for the oxidation state of phosphorus

Using the Oxidation Number Calculation knowledge point

$$ x - 6 = -3 $$

$$ x = +3 $$

Answer:

What is the oxidation state of phosphorus in the polyatomic anion \(\text{PO}_3^{3-}\)?
If the oxidation state is positive just give the number (e.g. enter 1 for +1)
If the oxidation state is negative give the negative number (e.g. enter -1 for -1)
If the oxidation state is zero, enter 0
