Which of the following acid occurs in polymeric form?

Which of the following acid occurs in polymeric form?

  • A. \( H P O_{3} \)
  • B. \( H_{4} P_{2} O_{7} \)
  • C. \( H_{3} P O_{4} \)
  • D. none of these

Step-by-step solution

Metaphosphoric acid (HPO3) exists in polymeric forms, such as cyclic trimers or longer chains, while H4P2O7 is a dimer and H3PO4 is monomeric. Hence, only HPO3 occurs in polymeric form.
