A hot water solution containing 73.1% (mass) of NaOH is a eutectic that solidifies at about 62.63 °C as an intimate mix of anhydrous and monohydrate crystals. [19] [18] A second stable eutectic composition is 45.4% (mass) of NaOH, that solidifies at about 4.9 °C into a mixture of crystals of the dihydrate and of the 3.5-hydrate. [11]
Capsaicin ( 8-methyl-N-vanillyl-6-nonenamide) ( / kæpˈseɪsɪn / or / kæpˈseɪəsɪn /) is an active component of chili peppers, which are plants belonging to the genus Capsicum. It is a chemical irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact.
Botulinum toxin, or botulinum neurotoxin (commonly called botox), is a highly potent neurotoxic protein produced by the bacterium Clostridium botulinum and related species. [23] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. [24]
Foodborne illness (also called food poisoning) occurs when we ingest harmful bacteria, chemicals, viruses or parasites. That happens when our food is contaminated, and it can happen in a number of ...
Lye. A lye is an alkali metal hydroxide. Traditionally, it was obtained by using rainwater to leach wood ashes, which are strongly alkaline and highly soluble in water, of their potassium hydroxide (KOH), producing lye water, a caustic basic solution. Then the lye water would either be used as such, as for curing olives before brining them, or ...
All who fell ill had eaten at the same Mexican restaurant in Pontiac, Michigan, and had consumed a hot sauce made with improperly home-canned jalapeño peppers, either by adding it to their food, or by eating nachos that had been prepared with the hot sauce. The full clinical spectrum (mild symptomatology with neurologic findings through life ...
Merbromin (marketed as Mercurochrome, Merbromine, Mercurocol, Sodium mercurescein, Asceptichrome, Supercrome, Brocasept and Cinfacromin) is an organomercuric disodium salt compound used as a topical antiseptic for minor cuts and scrapes and as a biological dye. Readily available in most countries, it is no longer sold in Switzerland, Brazil ...
Contact process. The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium (V) oxide (V 2 O 5) is now preferred.
