Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut ...
Phosgene reacts with water to form carbon dioxide and HCl, [77] and the carbonate salt neutralizes the resulting acid. [ 78 ] Suspected samples can be tested for phosgene using filter paper which when treated with 5% diphenylamine , 5% dimethylaminobenzaldehyde in ethanol , and then dried, turns yellow in the presence of phosgene vapour.

Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. [1]
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
Though one's body produces peptides naturally, peptides are also found in many food and supplement sources. "All the food we eat is broken down by the body into amino acids," explains Stevenson.
A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. [1] Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. [1] They are either cyanide- or arsenic-based. [1]
Traces of a toxic, colorless gas were found at the headquarters of Sweden’s security agency where a suspected gas leak last week forced authorities to evacuate some 500 people from the facility ...
To try and define "nature" is, to use a variety of hackneyed natural metaphors, to stir up a hornet's nest, or to stumble into a quagmire, to step into a snakepit, or, maybe more to the point, to ...
