- A \(\mathrm{H}_3 \mathrm{PO}_4\)
- B \(\mathrm{HPO}_3\)
- C \(\mathrm{H}_2 \mathrm{PO}_3\)
- D \(\mathrm{H}_3 \mathrm{PO}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{HPO}_3\)
Step-by-step Solution
Detailed explanation
The molecular formula of metaphosphoric acid is \(\mathrm{HPO}_3\). It's structure can be given as : It has general formula \(\left(\mathrm{HPO}_3\right)_n\). where, \(n\) denotes number of phosphoric acid units present in the ring, with \(n=3\) or more. In metaphosphoric acid…
