Sodium bicarbonate is widely used in laboratory settings as an analytical-grade reagent, particularly in acid-base titrations and as a buffering agent in biochemical assays. Its mild alkalinity makes it suitable for applications in food science, where it acts as a leavening agent in baking. Additionally, it is utilized in the pharmaceutical industry for the formulation of effervescent tablets and as an antacid for treating heartburn. Beyond the laboratory, sodium bicarbonate is also employed in environmental applications, such as neutralizing acidic soils and water bodies.
