Sodium bromideyog ib qho inorganic compound nrog cov tshuaj mis NaBr. Nws muaj nyob rau hauv cov xim tsis muaj xim cubic crystals lossis cov hmoov dawb granular, tsis muaj ntxhiab nrog ntsev thiab me ntsis iab saj. Sodium bromide feem ntau nqus cov dej noo los ntawm huab cua thiab tsim cov clumps, txawm hais tias nws tsis deliquesce. Nws yog heev soluble nyob rau hauv dej, yielding ib qho kev daws teeb meem nruab nrab, thiab me ntsis soluble nyob rau hauv cawv. Thaum reacted nrog dilute sulfuric acid, nws tsim hydrogen bromide. Nyob rau hauv acidic mob, sodium bromide tuaj yeem oxidized kom tso tawm elemental bromine.
Hauv kev siv tshuab thaij duab, sodium bromide feem ntau ua ob txoj haujlwm: ua tus neeg sawv cev photosensitive thiab ua tus neeg sawv cev tsim kho.
Ua ib tug photosensitive neeg sawv cev,sodium bromideua rau muaj peev xwm kaw cov duab los ntawm kev cuam tshuam los ntawm lub teeb. Thaum raug rau ultraviolet lossis lub teeb pom kev zoo, sodium bromide dhau los ua cov tshuaj tiv thaiv photochemical los tsim cov duab nrog cov yam ntxwv tshwj xeeb. Nws ua lub luag haujlwm tseem ceeb hauv kev thaij duab zaj duab xis ib txwm muaj thiab kev thaij duab digital, tshwj xeeb tshaj yog hauv kev tsim cov yeeb yaj kiab dub thiab dawb thiab xim.
Ua ib tus neeg sawv cev tsim kho, sodium bromide ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim zaj duab xis. Thaum lub sijhawm tsim kho, nws cuam tshuam nrog cov nyiaj ions hauv cov emulsions photosensitive los tsim cov nyiaj bromide, yog li ua rau pom cov duab latent rau hauv cov duab pom. Daim ntawv thov no tso cai rau cov kws thaij duab kom ua tiav qhov tseeb dua thiab cov ntsiab lus zoo hauv lawv cov duab. Tsis tas li ntawd, kev tswj hwm kev nce ntxiv ntawm bromide ion concentration pab tiv thaiv kev yaj ntawm cov nyiaj halides tsis tau pom, yog li tswj hwm qhov nrawm ntawm kev tsim kho thiab tiv thaiv kev hloov pauv tshuaj tsis xav tau.
Hauv kev xaus lus, sodium bromide lub luag haujlwm ob zaug hauv kev ua kom pom kev zoo thiab kev tsim duab tau yog qhov tseem ceeb rau kev siv tshuab thaij duab, ua rau muaj kev ntes thiab nthuav qhia cov duab pom.
