Uses:
Agriculture:Phosphoric acid is the raw material for the product of important Phosphate fertilizer(superphosphate,potassium dihydrogen phosphate,etc.),as well As the raw material for the production of feed nutrition agent(Calcium dihydrogen Phosphate).
Industry:Phosphoric acid is an important chemical raw material for food:Phosphoric Acid is one of the food additives,which is used as an acid flavor agent and yeast Nutrition agent in food. Coca Cola contains phosphoric acid. Phosphates are also Important food additives and can be used as nutrient enhancers.
Medicine:Phosphoric acid can be used to make phosphorous drugs,such as sodium Glycerophosphate.
