Problem

\text{H}_2\text{O}_2

is reduced rapidly by

\text{Sn}^{2+}

, the products being

\text{Sn}^{4+}

and water.

\text{H}_2\text{O}_2

decomposes slowly at room temperature to yield

\text{O}_2

and water. Calculate the volume of

\text{O}_2

produced at

20^\circ\text{C}

and 1.0 atm when 200 g of 10% by mass

\text{H}_2\text{O}_2

in water is treated with 100 millilitre of 2.0

\text{M}

\text{Sn}^{2+}

and then the mixture is allowed to stand until no further reaction occurs.
