Gynecologists have long been aware of the importance of maintaining a normal pH.
International Organization for Standardization: Quantities and units--Part 8: physical chemistry and molecular physics, Annex C (normative): pH.
Chemical reactions and enzyme activity occur more readily at a specific pH.
These sensors act as a small battery, generating a voltage signal proportional to the solution pH.
Emulsions containing LMW-chitosan showed no flocculation at this pH.
2] to the soil solution has less effect on solution ionic strength than 1 M KCl, and ionic strength has an inverse relationship with soil pH.
In the examples shown in Figure 2, the oxalate anion is the limiting ingredient; even low levels of calcium produce high levels of calcium oxalate precipitation at high pH.
Plants from areas with a Mediterranean climate like our own - where the year is divided into a short wet season followed by a long dry one - are partial to soil with an alkaline pH.
Figure 2 shows how absorbance and fluorescence of fluorescein change with solution pH.
The metal binds glucose when exposed to a blood sample modified to have a high, or strongly alkaline, pH.
Use strips of pH indicator paper to find a liquid with the same pH.
High temperatures caused rapid declines in sizing with the esterified size at high pH.
