Exempel på hur man kan använda ALKALINITY i en mening

• Søren Peter Lauritz Sørensen (9 January 1868 – 12 February 1939) was a Danish chemist, known for the introduction of the concept of pH, a scale for measuring acidity and alkalinity.
• A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH.
• While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology".
• Neutralizing the alkalinity of basic developers also helps to preserve the strength of the fixer, making it last longer.
• For example, alkalinity can lead to denaturation of DNA, instability of the plasma membrane and inactivation of cytosolic enzymes, as well as other unfavorable physiological changes.
• After the hypertufa object is completely cured, it is removed from the plastic, rinsed thoroughly, and allowed to sit exposed to the elements for several more weeks to reduce its otherwise-toxic surface alkalinity.
• Although alkalinity is primarily a term used by limnologists and oceanographers, it is also used by hydrologists to describe temporary hardness.
• Freshwater lakes with Dreissena are mesotrophic - high pH, moderate alkalinity, and have moderate amounts of dissolved minerals.
• Lime and ash are highly alkaline: the alkalinity helps the dissolution of hemicellulose, the major glue-like component of the maize cell walls, and loosens the hulls from the kernels and softens the maize.
• In his widely used method for the quantitative determination of carbonic acid the gaseous mixture is shaken up with baryta or limewater of known strength and the change in alkalinity ascertained by means of oxalic acid.
• A 1970 book on animal breeding claimed that does' milk differs from cows' or humans' milk by having higher digestibility, distinct alkalinity, higher buffering capacity, and certain therapeutic values in human medicine and nutrition.
• The alkalinity concentration of the waters of the creek ranged from 20 to 25 milligrams per liter in the 1950s and 1960s, but decreased to 11 to 15 milligrams per liter by 1993.
• According to its method of preparation, turnsole produced a range of translucent colors from blue, through purple to red, depending on its reaction to the acidity or alkalinity of its environment, in a chemical reaction, not understood in the Middle Ages, that is most familiar in the litmus test.
• The probable mechanism of vitamin C reduction, intragastric pH elevated into alkalinity, would apply to all other PPI drugs, though not necessarily to doses of PPIs low enough to keep the stomach slightly acidic.
• Types of potentiometric titration include acid–base titration (total alkalinity and total acidity), redox titration (HI/HY and cerate), precipitation titration (halides), and complexometric titration (free EDTA and Antical #5).
• The converse is also possible as alleviation of alkalinity: electronegative atoms or species (such as fluorine or the nitro group) will have an "electron-withdrawal" effect and thereby reduce the basicity.
• Massive carbonates will precipitate when the postglacial upwelling carries the alkalinity and isotopically light carbon to the continents.
• The clay soils containing montmorillonite or smectite (swelling clays) are more subject to alkalinity problems than illite or kaolinite clay soils.
• Non-native fish have not survived in the lake because of its high alkalinity, although in the early 1900s during a period of higher lake levels and falling alkalinity, Largemouth bass (Micropterus salmoides) and Brown bullhead (Ameiurus nebulosus) became abundant in the lake for some years.
• The carbonate radicle reported is presumably calculated from the alkalinity determination and doubtless includes sulphides and possibly silicates.
