Balance the redox reaction between zinc and trioxonitrate (v) ion

1) hydrogen peroxide should be stored in dark bottles away from light

2) hydrogen peroxide should be stored in a cool place.

3) Drops of sodium phosphate may be added to inhibit its catalytic decomposition

Explanation:

Hydrogen peroxide is known to dissociate according to the equation;

2H2O2--->2H2O+O2.

This decomposition is facilitated by the following factors;

1) heat

2) light

3) presence of trace amounts of a catalyst

This implies that, if the user stores the hydrogen peroxide in a dark bottle, away from sunlight. It decreases its chances of decomposition.

Similarly, if the hydrogen peroxide bottle is stored in a cool environment, it is not decomposed by heat.

Lastly, drops of an inhibitor such as sodium phosphate may be added to inhibit the effect of any catalyst that may have mistakenly contaminated the hydrogen peroxide sample.
