What happens when ozone and hydrogen peroxide react?
The simplified aqueous peroxone equation combines ozone and hydrogen peroxide to form oxygen and water.
- Balanced equation
- O3(g) + H2O2(aq) -> 2O2(g) + H2O(l)
- Model and safety boundary
- The real pathway includes short-lived intermediates. OmniLab does not model them, reaction rate, or ozone exposure.
Your study goal: Balance the net equation and separate its oxygen gas cue from the real reaction pathway.
Open the prepared exampleThe exact supported pair opens in a beaker. Nothing runs until you select Analyze.
Supported prediction
O3(g) + H2O2(aq) -> 2O2(g) + H2O(l)
What the equation means
Ozone and hydrogen peroxide produce water and oxygen in the simplified net equation for the aqueous peroxone process. The real pathway includes short-lived reactive intermediates that the current model does not represent. Oxygen evolution can bubble.
Expected observation
Oxygen evolution can produce bubbles
Oxygen evolution can produce bubbles. The virtual bubble cue does not measure gas volume or show the intermediate reactions.
Read the equation
Three details that explain the result
Connect the coefficients and formulas to the gas, solution, and visible cue.
-
Count oxygen atoms
O3 and H2O2 supply five oxygen atoms. Two O2 molecules and one H2O contain the same total.
-
Count hydrogen atoms
H2O2 supplies two hydrogen atoms. They appear together in the single water molecule.
-
Read the model boundary
The balanced net equation summarizes products. It does not describe the short-lived reactive species in real peroxone chemistry.
Three safety notes
Read these before any physical experiment
- 01
Use contained, ventilated ozone equipment in a specialist setup.
- 02
Prevent ozone inhalation and keep both oxidizers away from combustibles.
- 03
Do not seal the vessel because oxygen gas is produced.
Common questions
What students usually ask next
Use these distinctions to move from the visible reaction to the particle-level explanation.
What gas does the model predict?
It predicts oxygen gas, O2, in the simplified net equation.
Does the equation show every reaction step?
No. The real aqueous pathway includes short-lived intermediates outside this deterministic model.
