s a veterinary drug, as an antiepileptic medication for dogs and cats.
Under standard conditions, potassium bromide is a white crystalline powder. It is freely soluble in water. In a dilute aqueous solution, potassium bromide tastes sweet, at higher concentrations it tastes bitter, and at even higher concentrations it tastes salty. These effects are mainly due to the properties of the potassium ion—sodium bromide tastes salty at any concentration. In high concentration, potassium bromide strongly irritates the gastric mucous membrane, causing nausea and sometimes vomiting (a typical effect of all soluble potassium salts). chemical used as a restrainer in most developing solutions and as a rehalogenizing agent in bleaches.
In addition to manufacture of silver bromide, potassium bromide is used as a restrainer in black and white developer formulas. It improves differentiation between exposed and unexposed crystals of silver halide, and thus reduces fog
Plain collodion USP (Not the flexible collodion)

Collodion is a flammable, syrupy solution of pyroxylin (a.k.a. “nitrocellulose”, “cellulose nitrate”, “flash paper”, and “gun cotton”) in ether and alcohol. There are two basic types; flexible and non-flexible. The flexible type is often used as a surgical dressing or to hold dressings in place. When painted on the skin, collodion dries to form a flexible nitrocellulose film. While it is initially colorless, it discolors over time. Non-flexible collodion is often used in theatrical make-up.
(Dutch-ether German-Äther French – l’éther Spanish- éter )
IUPAC Name: oxidane
Ethers (pron.: /ˈiːθər/) are a class of organic compounds that contain an ether group — an oxygen atom connected to two alkyl or aryl groups — of general formula R–O–R’.A typical example is the solvent and anesthetic diethyl ether, commonly referred to simply as “ether” (CH3-CH2-O-CH2-CH3). Ethers are common in organic chemistry and pervasive in biochemistry, as they are common linkages in carbohydrates and lignin.
(Dutch-zilvernitraat German-Silbernitrat French -nitrate d’ argent Spanish- nitrato de plata )
IUPAC Name: silver nitrate
Silver nitrate is an inorganic compound with chemical formula AgNO3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called lunar caustic because silver was called luna by the ancient alchemists, who believed that silver was associated with the moon. The crystals are colourless and dissolve easily in water. If the water is pure, the solution can be kept indefinate, even in light. Silvernitrate stains – but stains on fabric can be removed with a solution of 10% iodide, leave for a few minutes (it will turn blue/ black), wash in a strong fix, then with lots of water.
(Dutch- ijzer sulfaat, groene vitriool German-Eisensulfat French -sulfate ferreux Spanish- sulfato ferroso)
IUPAC Name: iron; sulfuric acid
Iron(II) sulfate (Br.E. iron(II) sulphate) or ferrous sulfate is the chemical compound with the formula FeSO4. It is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol, the blue-green heptahydrate is the most common form of this material. All iron sulfates dissolve in water to give the same aquo complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic.
Glacial acetic acid (Crystals)
(Dutch-azijnzuur (ijsazijn) German-Eisessig French – l’acide acétique glacial Spanish-ácido acético glacial )
IUPAC Name: acetic acid
Acetic acid pron.: /əˈsiːtɨk/ (systematically named ethanoic acid pron.: /ˌɛθəˈnoʊɨk/) is an organic compound with the chemical formula CH3CO2H (also written as CH3COOH or C2H4O2). It is a colourless liquid that when undiluted is also called glacial acetic acid. Acetic acid is the main component of vinegar (apart from water; vinegar is roughly 8% acetic acid by volume), and has a distinctive sour taste and pungent
