what is the oxidation state of phosphorus in the compound na₃po₃?\na) 0\nb) -3\nc) +3\nd) +5

Answer

Explanation:

Step1: Recall oxidation - state rules

The oxidation state of sodium (Na) is +1 and the oxidation state of oxygen (O) is -2 in most compounds. Let the oxidation state of phosphorus (P) be (x).

Step2: Set up an equation based on the neutral - compound rule

For the compound (Na_3PO_3), the sum of the oxidation states of all atoms must equal zero. There are 3 Na atoms, 1 P atom, and 3 O atoms. So, (3\times(+ 1)+x + 3\times(-2)=0).

Step3: Solve the equation

First, expand the left - hand side: (3 + x-6 = 0). Then simplify to get (x-3 = 0). Solving for (x), we find (x = + 3).
