Question & Answer
  • Ambiguous oxidation state of phosphorus in phosphorous acid I was doing a question in which we were required to find the oxidation state of H X 3 P O X 3 " style="position: relative;" tabindex="0" id="MathJax-Element-2-Frame" class="MathJax" H X 3 P O X 3 H X 3 P O X 3 . I knew the structure that is: Now, phosphorus being less electronegative than oxygen ge...more+ Oct 28 2021
  • n-Factor of phosphorous acid It's very confusing that while H X 2 S O X 4 H X 2 S O X 4 has an n n -factor of 2, whereas H X 3 P O X 3 H X 3 P O X 3 has n n -factor 2 instead of 3. Many tried explaining it to me by molecular structures, but I don't know how to draw them. Could you please try explaining without the help of mole...more+ Aug 19 2021
  • Why is phosphorous acid diprotic and not triprotic? [closed] The two isomers you're referring to both exist and are in equilibrium: When only one or two protons are removed, resonance stabilizes the anions formed, e.g. the H P H O X 3 X − " style="position: relative;" tabindex="0" id="MathJax-Element-6-Frame" class="MathJax" H P H O X 3 X ?
