Phosphorus is one of the essential macronutrients for plants, playing a critical role in various biological processes, including energy transfer, photosynthesis, and synthesis of nucleic acids. This chemical element, represented by the symbol 'P' in the periodic table, is primarily found in the form of phosphate (PO4) in nature. Phosphoric acid (H3PO4), a key compound containing phosphorus, is widely used in fertilizers, food additives, and various industrial applications. Understanding the significance of phosphorus and phosphoric acid is crucial for both agriculture and several industrial sectors.
The effectiveness of the active form is 74.6% at pKa=4.8. The food additive must contain a minimum of 99% active substance relative to dry matter, aldehydes maximum 0.1% expressed as formaldehyde, loss on dehydration maximum 1% (at 1050C for 3 hours), and acidity 1% expressed as ascorbic acid.
