Define and illustrate the term clearly and concisely primary standard. Describe the composition and functions of glycerophospholipids. What do you understand by the term diffusion of gases? Explain what is meant by the term amphoteric. Give an example of a compound that fits ...
What immediatelycatches the careful reader's eyeis thatthe term elementis applied only to the first class of substances, and throughout the book only the members of this category are calledelements or principles, the other members of the table being called either simple bodies or “oxydable or...
Throughout the manuscript, the word ‘metastability’ refers to a sample condition describing a stable state of a dynamical system other than the system’s state of least energy. Depending on the context, the term applies both to phase equilibria and electronic defect states. The starting point ...
The term “zinc buffering” is based on the pH buffering concept, where an appropriate pH value is controlled by the ratio between a protonated form (HA), formally an acid according to the Brønsted–Lowry theory, and a deprotonated form of the buffer component (A−), formally a base,...
The personal care composition herein may include from 5% to 50% of an anionic, zwitterionic, and/or amphoteric detersive surfactant. The concentration of the detersive surfactant in the composition should be sufficient to provide the desired cleaning and lather performance. Some non-limiting examples...
The term “hand dish active” or “HDA” is used herein in the broadest sense to include any active that is suitable for cleaning and/or imparting other benefits to the items to be washed. Film-Forming Water-Soluble Polymer The article comprises at least one film-forming water-soluble ...
[21] used the term “fouling” to refer to the formation of a layer of impuri-ties on the surface of the ion exchange membrane (IEM) and “poisoning” to refer to their penetration inside the membrane. In some cases, there is a confusion between the terms “clogging” and “fouling”....
There is nothing more fundamental than clean potable water for living beings next to air. On the other hand, wastewater management is cropping up as a challenging task day-by-day due to lots of new additions of novel pollutants as well as the development
alkali precipitates an amphoteric yellow-brown hydroxide of trivalent gold, Au(OH)3, with mainly acidic properties; for this reason, the hydroxide is called auric acid and its salts, aurates. Heat converts auric hydroxide (trivalent gold) to auric oxide, Au2O3, which decomposes above 200°C:...
it may be possible to overcome application problems while lowering environmental and human health hazards. Additionally, it was believed that the creative fusion of these two very different sorts of materials would produce a variety of property improvements in addition to structural diversity. The main...
