Phosphoric acid orthophosphoric acid, monophosphoric acid or phosphoric V acid is a colorless, odorless phosphorus -containing solid , and inorganic compound with the chemical formula H 3 P O 4. It is a major industrial chemical, being a component of many fertilizers. The compound is an acid. Phosphoric acid forms esters , called organophosphates. The name "orthophosphoric acid" can be used to distinguish this specific acid from other " phosphoric acids ", such as pyrophosphoric acid. Nevertheless, the term "phosphoric acid" often means this specific compound; and that is the current IUPAC nomenclature. Phosphoric acid is produced industrially by one of two routes, wet processes and dry.

Phosphorous acid or phosphonic acid is the compound described by the formula H 3 PO 3. This acid is diprotic readily ionizes two protons , not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO 3 H 2 , are called phosphonic acids. In contrast, arsenous acid 's major tautomer is the trihydroxy form. On an industrial scale, the acid is prepared by hydrolysis of phosphorus trichloride with water or steam: [5]. HPO OH 2 could be produced by the hydrolysis of phosphorus trioxide :. Phosphorous acid has a p K a in the range 1. The hydrogen atom bonded directly to the phosphorus atom is not readily ionizable. Chemistry examinations often test students' appreciation of the fact that not all three hydrogen atoms are acidic under aqueous conditions, in contrast with H 3 PO 4. This reaction is used for laboratory-scale preparations of PH 3. Phosphorous acid slowly oxidizes in air to phosphoric acid.

Direct link to this balanced equation:. A chemical equation represents a chemical reaction. It shows the reactants substances that start a reaction and products substances formed by the reaction. However, this equation isn't balanced because the number of atoms for each element is not the same on both sides of the equation. A balanced equation obeys the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction. This is the most straightforward method. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. Process: Start with the most complex molecule or the one with the most elements, and adjust the coefficients of the reactants and products until the equation is balanced. This method uses algebraic equations to find the correct coefficients.

Take your experimental yield and divide it by the theoretical yield. The percent yield definition is that it is a measure of the effectiveness of a synthetic procedure. Chris British Dental Journal. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. At higher concentrations the freezing point rapidly increases. Now that's not great. Cosmetic ingredient dictionary. Hypochlorous acid. Let's assume you have both values; how to find the percent yield? Phosphoric acid may also be used for chemical polishing etching of metals like aluminium or for passivation of steel products in a process called phosphatization. Source: Fractional Crystallization. HPO OH 2 could be produced by the hydrolysis of phosphorus trioxide :. Phosphoric acid is not a strong acid.

In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid. Hydrobromic acid. The process begins with the slow cooling of the heat transfer medium below the freezing point of the stagnant melt. Discount Calculator. Activation Energy Calculator. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. HPO OH 2 could be produced by the hydrolysis of phosphorus trioxide :.
