The most common form is orthophosphoric acid. About 80% of produced phosphoric acid is used in agriculture, 10% as additives in cleaners, pesticides, and animal feed, and the remaining 10% is food-grade (carbonated beverages).<\/strong><\/p>\n<p><strong>The price of food-grade phosphoric acid depends on factors such as the dollar exchange rate, purity percentage, manufacturer brand, quality, and seller margin.
