description Product Description
Sodium bicarbonate is widely used in baking as a leavening agent. When mixed with acidic ingredients, it releases carbon dioxide, causing dough to rise. It is also employed in fire extinguishers to smother small grease or electrical fires by releasing carbon dioxide. In medicine, it serves as an antacid to neutralize stomach acid and relieve heartburn or indigestion. Additionally, it is used in cleaning products as a mild abrasive and deodorizer for surfaces and fabrics. In personal care, it is found in toothpaste for its whitening properties and in deodorants to neutralize odors. It is also utilized in water treatment to balance pH levels and in agriculture as a fungicide and soil conditioner.
