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.
