The phrase "acidity concentration" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or food science when discussing the amount of acid present in a solution or substance.
Example: "The acidity concentration of the solution was measured to determine its suitability for the experiment."
Alternatives: "acid concentration" or "level of acidity".
All significant parameters that influence the efficiency of the system such as sample acidity, concentration of complexing reagent and extraction solvent, flow-rate of disperser and sample solution as well as the preconcentration time were investigated and optimized by full factorial design.
Preliminarily, a factorial design was carried out in which the independent variables were transmembrane pressure (40, 50 and 60 bar) and temperature (20, 30 and 40 °C) of the process, and the dependent variables were pH, content of soluble solids, acidity, concentration of phenolic compounds and those of monomeric and total anthocyanins, colour index, colour density, and permeate flux.
It is known that the key factor for achieving perfectly ordered AAM with desired pitch is controlling the balance between the growth and the dissolution of the oxide film by adjusting the acidity, concentration, and temperature of anodization electrolytes[38], as well as modulating the applied voltages around the matching value approximately 0.4 V/nm[36].
In this agro-ecology, rice is cultivated during the rainy season when freshwater flows in the rivers and salt and acidity concentrations have reduced to non-toxic levels.
The particle strong acidity concentrations were highest in regions close to the high sulfur emission areas of the United States; that is, in the area immediately to the west of the Appalachian Plateau and west of the Allegheny Mountains (western Pennsylvania, eastern Ohio, and West Virginia) up through southern Ontario.
The affecting factors, including solution acidity, uric acid concentration and interfering substances, on the detection of uric acid using this probe are examined.
It is co-localized with major QTLs for pH, titratable acidity (TA), organic acids concentration and with small QTLs for sugars concentration [ 14].
Using a peach progeny of 208 F2 trees, the D locus was mapped to the proximal end of linkage group 5 and co-localized with major QTLs involved in the control of fruit pH, titratable acidity and organic acid concentration and small QTLs for sugar concentration.
Total acidity was used as an indirect measurement of citric acid concentration, the dominant acidic compound in Citrus fruit juice and major responsible of fruit acidity [ 9].
The acidity was generally low, with the highest acid concentration recorded in Nigerian pineapple (0.54 %) while American apple had the lowest acid concentration of 0.07%%.
Larger animals such as squid and fishes may also feel the effects of increasing acidity as carbonic acid concentrations rise in their body fluids.
