NaBr crystallizes in the same cubic motif as NaCl, NaF and NaI. The anhydrous salt crystallizes above 50.7 °C.[7] Dihydrate salts (NaBr·2H2O) crystallize out of water solution below 50.7 °C.[8] NaBr is produced by treating sodium hydroxide with hydrogen bromide. Sodium bromide can be used as a source of the chemical element bromine. This can be accomplished by treating an aqueous solution of NaBr with chlorine gas: ...

Nucleophillic Substitution Conclusion we all know that dipoles exsist because last lesson we were doing some hardcore chem-cooking What is it? Why is this relevant? and each end has positive and negative polarities due to electronegativity i hope someones done cakes this week :/ we were cooking some delicious brews of 1-bromobutane so we started off wtih the butan-1-ol then chucked in some water and sodium bromide C-C-C-C-OH - H - - - - - - - - H H H H H H H H H H O Na Br just incase you didnt know ;) then after adding the magic ingredient of sulphuric acid concentrated acid plus sodium bromide = hydrogen bromide :) this is when the magic happens C-C-C-C-OH - H - - - - - - - - H H H H H H H H because the bromide ion in hyrdogen bromide is more elctronegative than the hydroxide group when it approaches the butan-1-ol it strongly attracts the positive end of the molucule with its lone pairs dragging elctrons away from the hydroxide bond towards itself until evntually bye bye hydroxide hello ...

Oxidative treatment is one of the options to eliminate emerging pollutants (EPs) from drinking water or wastewater. For drinking water treatment, the ozonation technology is already implemented at many sites all around the world, so far mostly for disinfection purposes. However, in some countries such as the Netherlands surface water contains relatively high bromide concentrations, which leads upon reaction with ozone to the formation of bromate, a suspe cted carcinogen. In such a case, UV/H2O2 treatment is considered a useful alternative, despite the fact that energy requirements are substantially higher compared to treatment with ozone or O3 /H2O2. Only in recent years, the oxidative treatment of wastewat er has been investigated to not only protect our water resources, but also the ecosystem from pollution with chemicals used in our daily life. In Switzerland, the first permanent full scale plant with ozonat ion, WWTP Neugut in Dübendorf, is running since March 2014 . Its performance was ...
I came to the conclusion that adding 2ml/liter of a 5% solution of household ammonia to the salt fixer, the time is reduced to as few as 2 hours. In this recipe I also included 2g/l of Potassium Bromide which also contributes to the speeding of the salt fixer. But it may be left away, if time may be longer than 2 hours, let us say 4 hours. Also Potassium Bromide is not a household stuff and this is actually the aim of the thing, no need of expensive products and hard to get ...

Cytochrome bo forms complexes with chloride, bromide and iodide in which haem o remains high-spin and in which the 630 nm charge-transfer band is red-shifted by 7-8 nm. The chloride and bromide complexes each have a characteristic set of integer-spin EPR signals arising from spin coupling between haem o and CuB. The rate and extent of chloride binding decreases as the pH increases from 5.5 to 8.5. At pH 5.5 the dissociation constant for chloride is 2 mM and the first-order rate constant for dissociation is 2×10-4 s-1. The order of rate of binding, and of affinity, at pH 5.5 is chloride (1) , bromide (0.3) , iodide (0.1). It is suggested that the halides bind in the binuclear site but, unlike fluoride, they are not direct ligands of the iron of haem o. In addition, both the stability of the halide complexes and the rate of halide binding seem to be increased by the co-binding of a proton.. ...

Solid samples can be prepared in a variety of ways. One common method is to crush the sample with an oily mulling agent (usually Nujol) in a marble oragate mortar, with a pestle. A thin film of the mull is smeared onto salt plates and measured. The second method is to grind a quantity of the sample with a specially purified salt (usually potassium bromide) finely (to remove scattering effects from large crystals). This powder mixture is then pressed in a mechanical press to form a translucent pellet through which the beam of the spectrometer can pass. A third technique is the "cast film" technique, which is used mainly for polymeric materials. The sample is first dissolved in a suitable, non hygroscopic solvent. A drop of this solution is deposited on surface of KBr or NaCl cell. The solution is then evaporated to dryness and the film formed on the cell is analysed directly. Care is important to ensure that the film is not too thick otherwise light cannot pass through. This technique is suitable ...

For the next test Ive choosen a more delicate subject with a rather big contrast due to the strong side light and a dark surrounding. I didnt care for an EI 400 exposure but started with EI 800 going up to EI 3200. Development was 80 minutes in Caffenol-C-L with 1.2 g/l potassium bromide, 5 mins presoak , 24 °C pure stand development and agitation only for the first minute. Yes, 80 mins @ 24 °C! To keep the temperature I used a mantle bath with water of the same temperature. The stronger development should give the best film speed and more contrast, and the lack of any agitation after the first minute should avoid burnt highlights. When I took the wet negs out of the tank for drying I immediately knew: yep, thats it! The EI 800 exposure is spot on, almost no postprocessing needed, the grain is very fine for EI 800 and the contrast is simply perfect. No blown highlights at all. Base fog is still low enough for easy to enlarge wetprints, perfect even development. I was amazed. Rarely Ive ...

By: Jill Enfield. People usually think of doing tintypes in large format cameras such as 4 x 5 or 8 x 10s, but for years I have been encouraging students to use any type of camera they have on hand. Brownies and pinhole cameras have been used as well as something that has become a favorite - the Holga.. Dry plate tintypes are not faux tintypes. Gelatin emulsion tintypes were made commercially (by Kodak and others) as early as the 1880s. They were also made on paper and used in street cameras.. The emulsion bought today (such as AG plus) is similar to what you get when you make it from scratch using: gelatin, silver nitrate, potassium bromide and chrome alum.. I have been using dry plate tintype kits made by Rockland called the Rockloid AG Plus Tintype Parlor. It is very simple and the plates, which are actually aluminum, can be cut with a scissors so that they can fit into any camera. Since it is dry plate, no preparation needs to be done to the camera. Nothing will be dripped on or get ruined ...
I just got home from visiting with him and speaking to the vet. Gio is completely doped up, so was mostly unresponsive when I was there. But I got to give him lots of hugs and kisses at least. He has to stay overnight, and possibly tomorrow night as well. Lots of fluids, and depending how he is tomorrow morning, maybe some other treatment whose name has slipped my mind at the moment. Something about giving IV solution that competes with the Potassium Bromide and flushes it from the system quicker. So far, he doesnt need that, but if he doesnt improve much by tomorrow morning then it is a possibility ...
My husband and I are looking to adopt our first dog soon, and one online listing in particular has caught our eye. This dog is being rehomed because he has idiopathic epilepsy, which I understand means that he has seizures without any known cause. He is currently on phenobarbitol and potassium bromide but still seizes about once a month, usually at night while sleeping. We dont object to taking in a dog with special needs, in fact we would be happy to, but we want to be absolutely certain that we can handle this particular condition before we commit. I have done a lot of research already, but as much as I want to help him Im still not sure if this would be getting in over our heads. What advice do you have about living with and caring for an epileptic dog? Give me the lowdown dirty facts, please - Ive seen a lot of "you and your dog can still live a normal life" but I know that there would be bad days as well as good, and I feel it would be unfair to the dog if we didnt know that we were ...

K-BROVET potassium bromide is used to treat seizure disorders in dogs. Can be used in addition to therapy with other agents or as the sole anticonvulsant.
Reaction mechanism - Reaction mechanism - Unimolecular: Unimolecular nucleophilic substitution reactions proceed by a two-stage mechanism in which heterolysis precedes reaction with the nucleophile. The following equation is a typical example: in which the symbols are the same as in earlier equations, with the addition of delta plus (δ+) and delta minus (δ−), which indicate partial positive and negative charges, respectively. The significant consideration in this reaction mechanism is the initial separation of the bromide ion (by way of a transition state showing partial separation of the ion) to give a free positively charged organic ion (carbonium ion). This step is the rate-determining step of the reaction,
