Which of the following statements is not valid for oxo-acids of phosphorus?
1 Orthophosphoric acid is used in the manufacture of triple superphosphate
2 All oxo-acids contain tetrahedral four coordinated phosphorus
3 Hypophosphorus acid is a diprotic acid
4 All oxo-acids contains atleast one \(\mathrm{P}=\mathrm{O}\) unit and one \(\mathrm{P}\) - \(\mathrm{OH}\) group
Explanation:
Hypophosphorus acid is monoprotic acid as only one \(\mathrm{H}\) is attached on oxygen atom. \(\mathrm{H}\) atoms attached to \(\mathrm{O}\) are ionisable.
