Question

which oxyacid phosphorus has a tendency to show higher and lower oxidation state?​

Answer 1

Explanation:

bonds and P–OH bonds in oxoacids of phosphorus. In these cases, the oxidation state of phosphorus is less than +5. These acids are generally seen to jump to higher and lower oxidation states. For example, upon heating, phosphorous acid disproportionates to result in phosphoric acid and phosphine.

Answer 2

Oxyacids  of phosphorous : Oxidation state

Explanation:

Oxyacids

An oxyacid is defined as the acid that contains   oxygen atom bonded to a hydrogen atom and also has at least one other element.

Oxy-acids of phosphorous: Its oxy acids are :

• Hypo phosphorous acid (H₃PO₂)

• Phosphorous acid (H₃PO₃)

• Orthophosphoric acid (H₃PO₄)

• Peroxomonophosphoric acid (H₃PO₅)

• Metaphosphoric acid (HPO₃)

• Hypo phosphoric acid (H₄P₂ O₆)

• Pyro phosphoric acid (H₄P₂O₇)

• Pyro phosphorus acid (H₄P₂ O₅)

• Isohyphosphoric acid (H₄P₂ O₆)

The oxyacid of phosphorous with higher oxidation state is :

• Peroxomonophosphoric acid (H₃PO₅)

The oxyacid of phosphorous with lower oxidation state is :

• Hypo phosphorous acid (H₃PO₂)
