Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
This article needs to be updated.The reason given is: This is a historical article, primarily based on the Encyclopædia Britannica Eleventh Edition.Information on more recent methods should be integrated from Sodium hydroxide#Production, Chloralkali process, and others, to make this a workable overview of all the historical and modern methods.
Sodium deuteroxide or deuterated sodium hydroxide is a chemical compound with the formula Na O D or NaO 2 H. IUPAC recommends that the symbol for deuterium should be 2 H, [2] although most chemists use the term NaOD. It is a white solid very similar to sodium hydroxide, of which it is an isotopologue.
White liquor consists mainly of sodium hydroxide and sodium sulfide in water and is the active component in Kraft pulping. [1] White liquor also contains minor amounts of sodium carbonate, sodium sulfate, sodium thiosulfate, sodium chloride, calcium carbonate and other accumulated salts and non-process elements. These additional components are ...
Total ionic strength adjustment buffer (TISAB) is a buffer solution which increases the ionic strength of a solution to a relatively high level. This is important for potentiometric measurements, including ion selective electrodes, because they measure the activity of the analyte rather than its concentration.
Look for a soup that contains no more than 450 mg sodium per serving. View Recipe. Chicken Hummus Soup. Adding hummus to a soup may sound odd, but give it a try! It thickens up this 15-minute ...
The chemical reaction uses sodium hydroxide (NaOH), ferrosilicon, and water (H 2 O). While in the "silicol" process, a heavy steel pressure vessel is filled with sodium hydroxide and ferrosilicon, and upon closing, a controlled amount of water is added; the dissolving of the hydroxide heats the mixture to about 200 °F (93 °C) and starts the ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
