General description
Sodium Bicarbonate, also known as baking soda, is commonly used as a mild base to neutralize acidic spills, regulate pH levels, and counteract the effects of certain acidic toxins in the body. It also acts as a leavening agent by generating CO₂ when reacts with acidic ingredients like vinegar or lemon juice.
Application
- Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas.: This study utilizes sodium bicarbonate in a novel approach for the development of a contactless conductivity sensor. The sensor uses moist paper to absorb CO2 gas generated from sodium bicarbonate, demonstrating its potential for environmental monitoring and analytical applications (Sonsa-Ard et al., 2020).
Sodium bicarbonate is used as a:
- mild base to neutralize the reaction mixture during the synthesis of 1,2:5,6-Di-O-cyclohexylidene-D-mannitol, and 2,3-Cyclohexylidene-D-glyceraldehyde.
- precipitating agent in the co-precipitation method in the synthesis of gamma alumina (γ-Al2O3) catalyst during the methanol dehydration reaction to produce Dimethyl ether.
- a pore-forming agent and CO2 source to enhance the substrate porosity during the formation of a porous poly(ethersulfone) support layer for designing high-performance thin-film composite forward osmosis (TFC-FO) membranes.
