Question

Complete following reactions:

$$\begin{gathered} {\mathrm{P}}_2{\mathrm{O}}_5+{\mathrm{H}}_2\mathrm{O}\stackrel{}{\to }\mathrm{\_\_\_\_\_\_\_\_\_} \\ (\mathrm{phosphoric}\mathrm{acid}) \end{gathered}$$

Answer 1

Diphosphorus pentoxide reacts with water:

• Diphosphorus pentoxide(${\mathrm{P}}_2{\mathrm{O}}_5$) reacts with water(${\mathrm{H}}_2\mathrm{O}$) resulting in the formation of phosphoric acid(${\mathrm{H}}_3{\mathrm{PO}}_4$).
• $\underset{\mathrm{phosphorous}\mathrm{pentoxide}}{{\mathrm{P}}_2{\mathrm{O}}_5\left(\mathrm{s}\right)}+\underset{\mathrm{water}}{3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\stackrel{}{\to }\underset{\mathrm{phosphoric}\mathrm{acid}}{2{\mathrm{H}}_3{\mathrm{PO}}_4\left(\mathrm{aq}\right)}$
