Why does hydrogen peroxide produce bubbles and water when it reacts with soil

Answer 1

Hydrogen Peroxide (H₂O₂) is a strong oxidizing agent and oxidizes soil Carbon into Carbon Dioxide. However in doing so, H₂O₂ itself gets reduced into water at the same time. Thus, we observe bubbles (CO₂) and water when H₂O₂ comes in contact with soil.

Reaction: H₂O₂ + C (soil) --> H₂O + CO₂ (bubbles)
