Example of saponification reaction of a triglyceride molecule (left) with potassium hydroxide (KOH) yielding glycerol (purple) and salts of fatty acids ().. Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified.
For further details and instructions for use, see Template:Element cell/doc. Other templates are possible, displaying the data as one wishes. The neat things are the reader-friendly coding of the table cells, and the ability to copy an entire table code to another article and leave the data intact, just change the name of the template, and ...
That value is also the standard formation energy (∆G f °) for an Fe 2+ ion, since e − and Fe(s) both have zero formation energy. Data from different sources may cause table inconsistencies.
List of chemical elements — with basic properties like standard atomic weight, m.p., b.p., abundance; Abundance of the chemical elements; Abundances of the elements (data page) — Earth's crust, sea water, Sun and Solar System
It is an indicator of how much volatile fatty acid can be extracted from fat through saponification. It is equal to the number of milliliters of 0.1 normal alkali solution necessary for the neutralization of the water-insoluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.
The following list includes the metallic elements of the first six periods. It is mostly based on tables provided by NIST. [9] [10] However, not all sources give the same values: there are some differences between the precise values given by NIST and the CRC Handbook of Chemistry and Physics. In the first six periods this does not make a ...
Bring all the element articles to GA-class or above (turn the "Periodic Table by Quality" completely dark green and blue.) (104/124 = 83.9% as of August 2023) and in the longer(!) term: Bring all element articles to FA standard (turn the "Periodic Table by Quality" completely dark blue.) (22/124 = 17.7% as of August 2023)
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
