unusual facts about chloride



Abel Niepce de Saint-Victor

In 1804 the German chemist Adolph Ferdinand Gehlen (1775-1815) had noticed that when a solution of uranium chloride in ether was exposed to sunlight, it quickly changed color (from bright yellow to green) and precipitated.

Angel gilding

Justus von Liebig, widely credited with inventing the modern process for silvering glass, also worked on gilding glass with gold chloride.

Archibald Macallum

In 1901, he showed that the chromatin in cell nuclei contains iron, and in his early years at the University of Toronto he adapted measurement methods for a number of ions (chloride, potassium and phosphorus) for use with tissue and cell samples.

Benzethonium chloride

Independent testing shows that benzethonium chloride is highly effective against such pathogens as methicillin-resistant Staphylococcus aureus, Salmonella, Escherichia coli, Clostridium difficile, hepatitis B virus, hepatitis C virus, herpes simplex virus (HSV), human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), and norovirus.

Calcium chloride

Kelp is dried with calcium chloride for use producing sodium carbonate.

CFTR

Cystic fibrosis transmembrane conductance regulator, a protein involved in the transport of chloride ions across cell membranes or the gene that encodes this protein.

Cis effect

CO, AuPPh3, 3-NO3-

GABA receptor

The increased chloride conductance drives the membrane potential towards the reversal potential of the Cl¯ ion which is about –65 mV in neurons, inhibiting the firing of new action potentials.

Gallium chloride

Gallium trichloride (gallium(III) chloride/digallium hexachloride), GaCl3

Haloperoxidase

The Nernst equation shows that hydrogen peroxide can oxidize chloride (E°= 1.36 V), bromide (E°= 1.09 V) and iodide (E°= 0.536 V) from a thermodynamic perspective under natural conditions, i.e., a temperature range of about 0-30 °C and a pH ranging from about 3 (humic soil layer) to about 8 (sea water).

Heat-labile enterotoxin

In addition to its effects on chloride secretion, which involve the same steps as the effects of cholera toxin, heat-labile enterotoxin binds additional substrates: lipopolysaccharide on the surface of E. coli cells and A-type blood antigens.

Loop of Henle

:Sodium (Na+), potassium (K+) and chloride (Cl-) ions are reabsorbed from the urine by secondary active transport by a Na-K-Cl cotransporter (NKCC2).

Lubiprostone

Lubiprostone is a bicyclic fatty acid derived from prostaglandin E1 that acts by specifically activating ClC-2 chloride channels on the apical aspect of gastrointestinal epithelial cells, producing a chloride-rich fluid secretion.

Merle Randall

In 1932, Merle Randall authored two scientific papers with Mikkel Frandsen: “The Standard Electrode Potential of Iron and the Activity Coefficient of Ferrous Chloride,” and “Determination of the Free Energy of Ferrous Hydroxide from Measurements of Electromotive Force.”

Methylthioninium chloride

Methylthioninium chloride (INN, or methylene blue, proposed trade name Rember) is an investigational drug being developed by the University of Aberdeen and TauRx Therapeutics that has been shown in early clinical trials to be an inhibitor of Tau protein aggregation.

Monochloride

Bromine monochloride, also called bromine(I) chloride, bromochloride, and bromine chloride, BrCl

Na-K-Cl cotransporter

Put another way, increasing internal chloride concentration increases the reversal potential for chloride, given by the Nernst equation.

Oxalyl chloride

In March 2000, a Malaysia Airlines Airbus A330 was damaged beyond repair after a falsely declared cargo of oxalyl chloride leaked into the cargo bay.

Polyquat

n-alkyl-dimethyl benzyl ammonium chloride is also used in some disinfecting products such as wipes including those made by companies such as Clorox.

Reverse osmosis

An example of this process is Dasani, which adds sodium chloride (salt) and potassium chloride to its water for "taste", according to the company.

Rhenium chloride

Trirhenium nonachloride (rhenium(III) chloride/Rhenium trichloride), Re3Cl9

Sturge–Weber syndrome

Latanoprost is commercially formulated as an aqueous solution in a concentration of 0.005% preserved with 0.02% benzalkonium chloride (BAC).

Sulfuryl chloride

Sulfuryl chloride was first prepared in 1838 by the French chemist Henri Victor Regnault.

Swern oxidation

; Swern, D. title = Structure of the dimethyl sulfoxide-oxalyl chloride reaction product.

TBCC

Tribasic copper chloride, or Dicopper chloride trihydroxide, a copper compound widely used as a feed supplement

Yellow fluorescent protein

They have reduced chloride sensitivity, faster maturation, and increased brightness (defined as the product of the extinction coefficient and quantum yield).
