The reaction between soft soap and baking soda is a chemical reaction that produces carbon dioxide gas. This gas causes the mixture to fizz and bubble, and it can also be used to clean surfaces. The reaction can be represented by the following equation:

Na2CO3 + 2CH3COOH → 2NaCH3COO + H2O + CO2

In this equation, Na2CO3 is baking soda, CH3COOH is soft soap, NaCH3COO is the resulting soap, H2O is water, and CO2 is carbon dioxide gas.

The reaction between soft soap and baking soda is a simple one that can be performed at home. It is a good way to learn about chemical reactions and how they can be used to clean surfaces.
