Widely used as an antacid to neutralize stomach acid, providing relief from heartburn, indigestion, and upset stomach. It works by increasing the pH in the stomach, reducing irritation of the gastric lining. Also used as a laxative to treat occasional constipation by drawing water into the intestines and stimulating bowel movements. Commonly found in over-the-counter medications for digestive discomfort. In industrial settings, it serves as a flame retardant and smoke suppressant in plastics, rubber, and construction materials due to its ability to release water vapor when heated, which cools and dilutes flammable gases. Used in wastewater treatment to neutralize acidic effluents and remove heavy metals by precipitation. Its low toxicity and environmental compatibility make it suitable for pharmaceutical and environmental applications.
