\mathrm{(2) \, Hypophosphoric\: acid \rightarrow \mathrm{H}_4 \mathrm{P}_2 \mathrm{O}_6 \rightarrow 6 \, oxygen \, atoms}

\mathrm{(3) Phosphoric \, acid \rightarrow \mathrm{H}_3 \mathrm{PO}_4 \rightarrow 4\, oxygen \, atoms}

\mathrm{(4)\, Pyrophosphoric \, acid \rightarrow \mathrm{H}_4 \mathrm{P}_2 \mathrm{O}_7 \rightarrow 7\, oxygen \: atoms}
