It is light sensitive.
Silver nitrate is very susceptible to reactions that destroy it, catalyzed by short wavelength light, which is strongly absorbed by brown bottles.
Keep silver nitrate in brown bottles and/or cover the bottle with aluminium foil. This will prevent the decomposition of silver nitrate from light.
Potassium ferrocynide is stored in dark coloured bottels and kept away from sunlight.This is because it decomposes when exposed to sunlight.Thus it is always stored in amber or brown coloured bottels.
Silver compounds are mostly insoluble (except silver nitrate of course) so you can safely assume that the precipitate you obtained was a silver compound and knowing silver bromide forms a yellow precipitate, it is a good bet to guess there is bromide ions (note ions not bromine) present. your compound is likely a bromide salt rather than bromine water or pure bromine (i'm assuming this is a high school lab report). but if your test compound was fuming reddish brown fumes then it is probably bromine water
Because it is :)
Silver bromide reacts chemically when exposed to light, which is why they use it to make photographic papers.
Silver nitrate is slightly photosensitive. In order to prevent it from under going decomposition or maintain its self properties it is stored in brown bottles.
Silver bromide is a photo reactive substance, the colour of the bottle keeps light out.
Silver nitrate is very susceptible to reactions that destroy it, catalyzed by short wavelength light, which is strongly absorbed by brown bottles.
because it can decompose quickly if kept in transparent bottles
This is to avoid exposition to light and to minimize the formation of peroxides
well some foods and beverages (like rootbeer)are stored in brown bottles to keep them cold.the brown of the bottle reflects the sun away from the food or beverage to keep it nice and cold. :)
Keep silver nitrate in brown bottles and/or cover the bottle with aluminium foil. This will prevent the decomposition of silver nitrate from light.
For silver halogens Silver Fluoride ; No colour , remians in solution Silver Chloride ; White ppt Silver Bromide ; Cream/Pale yellow ppt Silver Iodide ; Yellow ppt. These are the classic test colours for silver halogens.
