Inert atmospheres consisting of gases such as argon, nitrogen, or helium are commonly used in chemical reaction chambers and in storage containers for oxygen-or water-sensitive substances, to prevent unwanted reactions of these substances with oxygen or water. [4] Argon is widely used in fluorescence tubes and low energy light bulbs.
In chemistry, a counterion (sometimes written as "counter ion", pronounced as such) is the ion that accompanies an ionic species in order to maintain electric neutrality. In table salt (NaCl, also known as sodium chloride) the sodium ion (positively charged) is the counterion for the chloride ion (negatively charged) and vice versa.
Placebos are typically inert tablets, such as sugar pills. A placebo (/ p l ə ˈ s iː b oʊ / plə-SEE-boh) is a substance or treatment which is designed to have no therapeutic value. [1] Common placebos include inert tablets (like sugar pills), inert injections (like saline), sham surgery, [2] and other procedures. [3]
An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. Though inert gases have a variety of applications, they are generally used to prevent unwanted chemical reactions with the oxygen ( oxidation ) and moisture ( hydrolysis ) in the air from ...
For example, precisely the same inert agents can produce analgesia and hyperalgesia, the first of which, on this definition, would be a placebo, and the second a nocebo. [31] A second problem is that the same effect, such as immunosuppression, may be desirable for a subject with an autoimmune disorder, but undesirable for most other subjects.
In many applications, the noble gases are used to provide an inert atmosphere. Argon is used in the synthesis of air-sensitive compounds that are sensitive to nitrogen. Solid argon is also used for the study of very unstable compounds, such as reactive intermediates, by trapping them in an inert matrix at very low temperatures. [91]
The inerting systems use an inert gas generator to supply inert make-up gas instead of air. This procedure is often referred to as inerting. Technically, the procedure ensures that the atmosphere in the tank's headspace remains unignitable. The gas mixture in the headspace is not inert per se, it's just unignitable. Because of its content of ...
