• A. True
• B. False

Answer 1

The correct option is A True

• Phosphorus pentaoxide dissolving in water forms phosphoric acid.
• The given reaction is
• $\underset{\mathrm{Pentaoxide}}{\underset{\mathrm{Phosphorus}}{{\mathrm{P}}_2{\mathrm{O}}_5\left(\mathrm{s}\right)}}+\underset{\mathrm{Water}}{3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Phosphoric}\mathrm{Acid}}{2{\mathrm{H}}_3{\mathrm{PO}}_4\left(\mathrm{aq}\right)}$.

Hence, the given statement is true.
