Identity the compound in which phosphorus exists in the oxidation state of +1
Identity the compound in which phosphorus exists in the oxidation state of +1
- A. Phosphonic acid \( \left(H_{3} P O_{3}\right) \)
- B. Phosphinic acid \( \left(H_{3} P O_{2}\right) \)
- C. Pyrophosphorus acid \( \left(H_{4} P_{2} O_{5}\right) \)
- D. Orthophosphoric acid \( \left(H_{3} P O_{4}\right) \)
Step-by-step solution
The oxidation state of phosphorus in phosphinic acid (H3PO2) is calculated as: 3(+1) + x + 2(-2) = 0 → x = +1. Therefore, phosphorus exhibits a +1 oxidation state in this compound.
