Observe the following stoichiometric equation P ₄+3 OH ⁻+3 H ₂ O PH ₃+3 x⁻ What is the conjugate acid of x⁻ ?

Options

  1. APhosphorous acid
  2. BHypophosphorous acid
  3. CPhosphoric acid
  4. DPyrophosphoric acid

Correct answer

B. Hypophosphorous acid

Step-by-step solution

Balanced stoichiometric equation is: P ₄+3 OH ⁻+3 H ₂ O PH ₃+3 H ₂ PO ₂⁻ conjugate of H ₂ PO ₂⁻ is H ₃ PO ₂ . H ₃ PO ₂ is hypophosphorous acid.
