Observe the following stoichiometric equation
\(\mathrm{P}_4+3 \mathrm{OH}^{-}+3 \mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{PH}_3+3 x^{-}\)
What is the conjugate acid of \(x^{-}\)?
- A Phosphorous acid
- B Hypophosphorous acid
- C Phosphoric acid
- D Pyrophosphoric acid
Answer & Solution
Correct Answer
(B) Hypophosphorous acid
Step-by-step Solution
Detailed explanation
Balanced stoichiometric equation is: \(\mathrm{P}_4+3 \mathrm{OH}^{-}+3 \mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{PH}_3+3 \mathrm{H}_2 \mathrm{PO}_2^{-}\) conjugate of \(\mathrm{H}_2 \mathrm{PO}_2^{-}\)is \(\mathrm{H}_3 \mathrm{PO}_2\). \(\mathrm{H}_3 \mathrm{PO}_2\) is…
