Used as a buffering agent in food and pharmaceutical formulations to maintain stable pH levels. Acts as a sequestrant, helping to bind metal ions and prevent oxidation in processed foods and beverages. Commonly found in baking powders, where it regulates the release of carbon dioxide by controlling the reaction rate with sodium bicarbonate. Employed in analytical chemistry as a component of Fehling's solution to detect reducing sugars. Also utilized in the textile industry for dyeing and printing processes due to its ability to stabilize solutions and improve color consistency.
