Why is it called bromide?
This use gave the word "bromide" its colloquial connotation of a boring cliché, a bit of conventional wisdom overused as a calming phrase, or verbal sedative. The bromide ion is antiepileptic, and bromide salts are still used as such, particularly in veterinary medicine. Bromide ion is excreted by the kidneys.
How do I make a bromide photo?
Prepare a normal bromide print, aiming for slightly veiled highlights and detail in the shadows. Leave a ½" to 1" margin all round the image for handling purposes. The developer I use to produce the image is the old D163 formula. All the chemical formulae are given at the end of this article.
What are the different uses of metal bromides?
Many metal bromides are produced commercially, including LiBr, NaBr, NH 4 Br, CuBr, ZnBr 2 and AlBr 3. Some applications are for silver-based photography, which is fading in value, and drilling fluid, which calls for generic, dense compounds and thus is of little value. Lithium bromide was used as a sedative beginning in the early 1900s.

When was lithium bromide used?
Lithium bromide was used as a sedative beginning in the early 1900s. However, it fell into disfavour in the 1940s due to the rising popularity of safer and more efficient sedatives (specifically, barbiturates) and when some heart patients died after using a salt substitute (see lithium chloride ).
How to test for bromide ion?
One can test for a bromide ion by adding excess dilute HNO 3 followed by dilute aqueous AgNO 3 solution. The formation of creamy silver bromide precipitate confirms the existence of bromides.
What is the concentration of bromide in the blood?
Bromide ion concentrations in the cerebrospinal fluid are about 30% of those in blood and are strongly influenced by the body's chloride intake and metabolism. Since bromide is still used in veterinary medicine in the United States, veterinary diagnostic labs can routinely measure blood bromide levels.
How to extract bromine from seawater?
Balard and Löwig's method can be used to extract bromine from seawater. First, a seawater sample is tested for the presence of bromide compounds. That same sample is then titrated with aqueous chlorine to produce pure bromine (Br 2 ).
What is the ionic radius of bromide?
The bromide ion has an ionic radius of 196 pm. It is the most stable ionic form of bromine; because of its size and small charge, it is highly polarizable .
When did bromide become a sedative?
Bromide compounds, especially potassium bromide, were frequently used as sedatives in the 19th and early 20th centuries. Their use in over-the-counter sedatives and headache remedies (such as Bromo-Seltzer) in the United States extended to 1975 when bromides were withdrawn as ingredients due to chronic toxicity.
Is bromide used for epilepsy?
Therapeutic bromide levels are measured in European countries like Germany, where bromide is still used therapeutically in human epilepsy. Chronic toxicity from bromide can result in bromism, a syndrome with multiple neurological symptoms. Bromide toxicity can also cause a type of skin eruption. See potassium bromide .

Brief overview
Very simply, the silver image in a black and white print is replaced by an ink image. The three basic steps are as follows:
Process
1 The print Kentmere Document Art paper is a good starting point (in the UK), about 8 inches x10 inches is ideal. Leave a clear margin of about half an inch all around to allow for handling. Try to start with an image that’s not too harsh in contrast. Aim for details in the shadows with veiled highlights.
Conclusion
Results will depend upon the brush type, the pressure the ink is applied, and the technique of the individual. Because the print is hand crafted, it is unique; no two images will be the same. For me, that is the beauty of the Bromoil process.
What is substrate in printing?
A substrate in printing is the actual paper, vinyl or other foam core that is getting printed and cut to size. It doesn’t matter what type of substrate you’re using, many designs still need to consider the bleed printing dimensions.
What is the bleed size for a photo?
As you might remember is usually .125 on each side. Keep everything important inside the safe zone and away from the bleed printing area.
Do you need a bleed on a business card?
If you have a plain white business card with your information in the center, and not close to the edge, you probably won’t need a bleed. This is true for flyers, banners, posters or anything. If you’re unsure, you can play it safe and add the bleed in printing, or ask customer support at your printer.
Do you need to bleed every side of a print?
There is another time when you might not need a bleed on every side of your printing project. One example of this is known as a printer spread. This is true for magazines, book covers or a newspaper. You will only need to set up a bleed for the outside edges.

Overview
A bromide ion is the negatively charged form (Br ) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. Although uncommon, chronic toxicity from bromide can result in bromism, a syndrome with multiple neurological symptoms. Bromide toxicity can also cause a type of skin eruption. See potassium …
Natural occurrence
Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to silver, bromine is also in minerals combined with mercury and copper.
Formation and reactions of bromide
Bromide salts of alkali metal, alkaline earth metals, and many other metals dissolve in water (and even some alcohols and a few ethers) to give bromide ions. The classic case is sodium bromide, which fully dissociates in water:
NaBr → Na + Br
Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with …
Applications
Bromide's main commercial value based on value and quantity is its use in producing organobromine compounds, which themselves are rather specialized. Organobromine compounds are mainly used as fire retardants, and even these applications are controversial. Many metal bromides are produced commercially, including LiBr, NaBr, NH4Br, CuBr, ZnBr2 and AlBr3. Some applications are for silver-based photography, which is fading in value, and drilling …
Medicinal and veterinary uses
Lithium bromide was used as a sedative beginning in the early 1900s. However, it fell into disfavour in the 1940s due to the rising popularity of safer and more efficient sedatives (specifically, barbiturates) and when some heart patients died after using a salt substitute (see lithium chloride). Like lithium carbonate and lithium chloride, it was used as a treatment for bipolar disorder.
Bromide compounds, especially potassium bromide, were frequently used as sedatives in the 19…
Biochemistry
Bromide is rarely mentioned in the biochemical context. Some enzymes use bromide as substrate or as a cofactor.
Bromoperoxidase enzymes use bromide (typically in seawater) to generate electrophilic brominating agents. Hundreds of organobromine compounds are generated by this process. Notable exampless are bromoform, thousands of tons of which are produced annually in this wa…
