The oxidation sate of phosphorus in hypophosphoric acid is

The oxidation sate of phosphorus in hypophosphoric acid is

The oxidation sate of phosphorus in hypophosphoric acid is

Correct answer

4

Step-by-step solution

Hypophosphoric acid ${H}_{4}{P}_{2}{O}_{6}$

The oxidation sate of phosphorus in hypophosphoric acid is

The oxidation state of phosphorus is

$⇒ 4 \times 1 + 2 \times x + 6 \times \left(- 2\right) = 0$

$⇒ 4 + 2x - 12 = 0$

$⇒ 2x - 8 = 0$

$⇒ 2x = 8$

$⇒ x = \dfrac{8}{2} = 4$
