Sodium bicarbonate is an inorganic salt with the chemical formula $\text{NaHCO}_3$. It is widely utilized in chemical and biological systems owing to its buffering capacity and basic nature. Chemically, the compound readily reacts with acids to produce salt, water, and carbon dioxide gas, a reaction that is fundamental in various industrial synthesis processes. In biochemistry, sodium bicarbonate plays a critical role in the bicarbonate buffer system, which helps maintain the physiological pH of aqueous biological fluids. Due to its solubility and buffering properties, it has applications in various fields, ranging from climate chemistry to the stabilization of industrial solutions.
