Uses of bases in our daily life: Ammonia: It is essential for maintaining the acid-base balance in your body and so keeps you healthy. It is used as a processing aid in thousands of food and beverage products. Explosive nitrogen is created from ammonia. Polymers acrylic and nylon use ammonia. Aluminum hydroxide uses: To treat symptoms of increased stomach acid, such as heartburn, upset stomach, sour stomach, or acid indigestion. To reduce phosphate levels in people with certain kidney conditions. Calcium hydroxide: Treats damaged teeth, especially immature permanent teeth, to preserve the living tissue. It is also used as an antibiotic during root canals. The food shipping and storage industries use calcium hydroxide as it keeps fruits from ripening before it can be shipped to grocery stores across the country. It is also used in iron refining. In paper manufacturing, it is one chemical within the bleaching process that makes paper white. It is even part of paper recycling, as a coagulant to help remove ink and dyes from waste paper before it is recycled into new paper. Sodium Hydroxide: Is also used quite a bit in food processing Is often used in steps for peeling fruits and vegetables, processing cocoa and chocolate, thickening of ice cream, poultry scalding and soda processing Olives are soaked in Sodium Hydroxide along with other substances to make them black It is also used in processes to make products including plastics, soaps rayon and textiles. Soft pretzels (kind of a baked food) are also coated with the compound to give them a Chewy texture.
