Our percent yield calculator will help you to understand how to calculate the percent yield , as well as teach you the percent yield formula and the percent yield definition. Finding the yield is an integral part of any kind of synthetic lab work as the percent yield equation turns your experimental yields into a representation of how successfully you carried out your reaction. Hopefully, after reading this page, you will have an answer to the questions "what is percent yield? What is the percent yield? The percent yield definition is that it is a measure of the effectiveness of a synthetic procedure. Wordy, right?

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. In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid. Calcium sulfate gypsum, CaSO 4 is a by-product, which is removed as phosphogypsum. The hydrogen fluoride HF gas is streamed into a wet water scrubber producing hydrofluoric acid. The phosphoric acid from both processes may be further purified by removing compounds of arsenic and other potentially toxic impurities. To produce food-grade phosphoric acid, phosphate ore is first reduced with coke in an electric arc furnace , to give elemental phosphorus. This process is also known as the thermal process or the electric furnace process. Silica is also added, resulting in the production of calcium silicate slag. Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide , which is dissolved in water to make phosphoric acid.

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.

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.

Enter either the number of moles or weight for one of the compounds to compute the rest. We know our experimental yield is 5. Now we know that if we carry out the experiment and get 5. Peter Don't be upset, though. Balancing the equation means the number of atoms of each elements must be equal on both sides. There are 2 O atoms on the left and 1 O atom on the right. Yes, we can divide both number by 2. Multiply this value by to find the percent yield. Retrieved 2 June The phosphoric acid also serves as a preservative. CAS Number. Phosphoric acid is H 3 PO 4 as given by the equation.
