Phosphoric acid is a phosphorus oxoacid that consists of one oxo and three hydroxy groups joined covalently to a central phosphorus atom. It has a role as a solvent, a human metabolite, an algal metabolite, a fertilizer and a NMR chemical shift reference compound. It is a conjugate acid of a dihydrogenphosphate and a phosphate ion.

偏磷酸是一种无机物，化学式HPO 3 ，分子量80，无色玻璃状体，易 潮解 ，密度2.2～2.5g/cm 3 ，易溶于水并生成正磷酸（H 3 PO 4 ）。 常见的偏磷酸是三聚偏磷酸（HPO 3 ） 3 和四聚偏磷酸（HPO 3 ） 4 ，其化学式均写简为HPO 3 。

2025年2月28日 · phosphoric acid, (H 3 PO 4), the most important oxygen acid of phosphorus, used to make phosphate salts for fertilizers. It is also used in dental cements, in the preparation of albumin derivatives, and in the sugar and textile industries. It serves as an acidic, fruitlike flavouring in food products.

2023年12月26日 · Phosphoric acid is represented as H 3 PO 4 or PO-(OH) 3. The structure of Phosphoric Acid consists of three hydroxyl groups (-OH), each single-bonded with the central phosphorus atom (P) and one oxygen atom which is in double-bond with the central available phosphorus atom (P).

Phosphoric Acid is a weak acid with the chemical formula H 3 PO 4. Phosphoric Acid is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen. It is also known as phosphoric (V) acid or orthophosphoric acid. It is present in teeth and bones and helps in metabolic processes.

2021年3月25日 · Polyphosphoric acid (H 3 PO 4) is a colorless, odorless and highly viscous liquid compound with strong hydroscopic properties. It is a mixture of linear phosphoric acids and orthophosphoric acid. Phosphoric acids with less than 95% H3PO4 (68% P2O5) contain the simple orthophosphoric acid.

Orthophosphoric acid (H 3PO 4), usually referred to as phosphoric acid, is a clear, water-white liquid which is derived from phosphate rock. Phosphoric acid is a triprotic acid which means that, in an aqueous solution, it will dissociate to produce three hydrogen ions. Phosphoric acid is a stronger acid than the organic acids, such as

无水磷酸是白色固体，在42.35 o C熔化成粘性液体。 在水溶液中，磷酸是三元酸，有三个可电离的氢原子。 工业上，磷酸可用于肥料、洗涤剂、药物、水软化剂。 塑料瓶包装. 浓磷酸大约为 85% H 3 PO 4 (水溶液)。 没有发现合适的版本？ 如果您需要特殊版本，可通过批号或批次号查找具体证书。 已有该产品？ 在文件库中查找您最近购买产品的文档。 Probing hot spots at protein-ligand binding sites: a fragment-based approach using biophysical methods.

Phosphoric acid H 3 PO 4 as a polyprotic acid is defined by the following three dissociation reactions and pK a values:
