What would happen if you mixed hydrogen peroxide and baking soda?

Mixing hydrogen peroxide and baking soda results in a chemical reaction that produces oxygen and carbon dioxide gases, along with water and sodium percarbonate. When the baking soda (sodium bicarbonate) is added to the hydrogen peroxide, the following reaction takes place:

```

NaHCO3 (sodium bicarbonate) + H2O2 (hydrogen peroxide) → CO2 (carbon dioxide) + H2O (water) + Na2CO3 (sodium percarbonate) + O2 (oxygen)

```

- Gas Production: The reaction leads to the formation of carbon dioxide and oxygen gases. These gases cause effervescence, foaming, and fizzing, resulting in a rapid release of bubbles and a significant increase in volume.

- Sodium Percarbonate Formation: Sodium percarbonate (Na2CO3) is also produced as a byproduct of the reaction. This compound is a mild oxidizing agent and can be used as a cleaning agent or bleaching agent.

- Effervescent Cleaning Action: The combination of gas production and the cleaning properties of sodium percarbonate makes this reaction useful for cleaning purposes. The oxygen and carbon dioxide gases help to loosen and lift dirt, while the sodium percarbonate acts as a mild abrasive and disinfectant.

It's important to note that this reaction should be carried out with caution. The rapid release of gases can cause a buildup of pressure, potentially leading to splashes or even container bursts if not handled properly. Therefore, it's recommended to conduct this reaction in an open container and to wear protective gloves and eye protection.
