2 AgBr (s) + 2 NH4OH (aq) --> Ag2O (s) + H2O (l) +2 NH4Br (aq)
The reaction does not proceed rapidly as in the case of AgCl as AgBr is only slightly soluble in ammonium hydroxide. With more NH4OH, the brown/black Ag2O dissolves forming the soluble salt Silver Di-amine hydroxide:
Ag2O (s) + 4 NH4OH --> 2 [Ag(NH3)2]OH + 3 H2O
I suspect that this reaction is reversible and the loss of NH3 would push the reaction to the left, which may occur naturally with time. This is a major problem as the precipitated Ag2O can further react with NH4OH to form Silver nitride, Ag3N:
2 NH4OH (aq) + 3 Ag2O (s) --> 2 Ag3N (s) + 5 H2O
Silver nitride can be a highly sensitive and powerful contact explosive, even when in solution. This has been ascribed to be the cause of many injuries, and as such, solutions of [Ag(NH3)2]OH should not be stored for safety concerns.

Laboratory observation of reaction between silver nitrate and sodium bromide?
When silver nitrate and sodium bromide are mixed together in a laboratory setting, a white precipitate of silver bromide is formed. This reaction is a double displacement reaction where the silver ions from silver nitrate combine with the bromide ions from sodium bromide to form an insoluble compound. The formation of the precipitate indicates that a chemical reaction has occurred.
Product of alcoholic silver nitrate with ethyl bromide reaction?
When ethyl bromide, an alkyl halide, reacts with alcoholic silver nitrate (AgNO3), silver bromide (AgBr) and ethanol are produced. This reaction is a substitution reaction where the bromine in ethyl bromide is replaced by the nitrate ion from silver nitrate.
What is the chemical reaction with silver nitrate and bromine?
The chemical reaction between silver nitrate and bromine results in the formation of silver bromide and nitric acid. The balanced chemical equation for this reaction is 2AgNO3 + Br2 -> 2AgBr + 2 HNO3. Silver bromide is a yellowish solid precipitate, and nitric acid is a byproduct of the reaction.
What is the balanced equation for silver bromide ammonium sulfate?
The balanced equation for the reaction between silver bromide and ammonium sulfate is: AgBr + (NH4)2SO4 -> Ag2SO4 + 2NH4Br
What is the precipitate when potassium bromide and silver nitrate are mixed?
The precipitate formed when potassium bromide and silver nitrate are mixed is silver bromide (AgBr), which is a white solid. This reaction is a double displacement reaction where the silver ions from silver nitrate exchange with the bromide ions from potassium bromide to form the insoluble silver bromide.
What happens when silver nitrate is added to bromide?
When silver nitrate is added to a solution containing bromide ions, a white precipitate of silver bromide will form. This is due to a chemical reaction between the silver nitrate and bromide ions, resulting in the insoluble silver bromide precipitate.
Laboratory observation of reaction between silver nitrate and sodium bromide?
When silver nitrate and sodium bromide are mixed together in a laboratory setting, a white precipitate of silver bromide is formed. This reaction is a double displacement reaction where the silver ions from silver nitrate combine with the bromide ions from sodium bromide to form an insoluble compound. The formation of the precipitate indicates that a chemical reaction has occurred.
Chloride-bromide against silver nitrate?
When chloride and bromide ions are mixed with silver nitrate, a white precipitate of silver chloride and a pale yellow precipitate of silver bromide are formed. This reaction is a qualitative test to distinguish between chloride, bromide, and nitrate ions.
What is the product of sodium bromide plus silver nitrate?
The reaction between sodium bromide and silver nitrate forms silver bromide and sodium nitrate. The product is a white precipitate of silver bromide, while sodium nitrate remains dissolved in the solution as a spectator ion.
What is the product of strontium bromide silver nitrate?
The product of strontium bromide and silver nitrate is strontium nitrate and silver bromide. This is because there is a double displacement reaction between the two compounds where the cations and anions switch partners.
What is the equation when ammonia reacts with silver nitrate?
The equation for the reaction between ammonia and silver nitrate is: 2NH3 + AgNO3 → AgNH3 + NO3
What are the products of the double-replacement reaction between potassium bromide and silver nitrate?
The products of the double-replacement reaction between potassium bromide (KBr) and silver nitrate (AgNO3) are silver bromide (AgBr) and potassium nitrate (KNO3). This reaction occurs because the positive ions (K+ and Ag+) exchange partners with the negative ions (Br- and NO3-) to form the two new compounds.
What happens in the reactions of aqueous bromide ions with aqueous silver nitrate following by the addition of concentrated aqueous ammonia?
When aqueous bromide ions react with aqueous silver nitrate, a white precipitate of silver bromide is formed. Upon addition of concentrated aqueous ammonia, the precipitate dissolves due to the formation of a complex ion called the diamminesilver(I) ion, [Ag(NH3)2]+. This reaction forms a colorless solution.
What is reaction between silver iodide and ammonia?
When silver iodide reacts with ammonia, a complex compound called silver diammine iodide is formed. This reaction involves the exchange of ligands between the silver ions and ammonia molecules, resulting in the formation of a soluble complex that is typically a pale yellow color.
Product of alcoholic silver nitrate with ethyl bromide reaction?
When ethyl bromide, an alkyl halide, reacts with alcoholic silver nitrate (AgNO3), silver bromide (AgBr) and ethanol are produced. This reaction is a substitution reaction where the bromine in ethyl bromide is replaced by the nitrate ion from silver nitrate.
What is the chemical reaction with silver nitrate and bromine?
The chemical reaction between silver nitrate and bromine results in the formation of silver bromide and nitric acid. The balanced chemical equation for this reaction is 2AgNO3 + Br2 -> 2AgBr + 2 HNO3. Silver bromide is a yellowish solid precipitate, and nitric acid is a byproduct of the reaction.
What is the effect of sunlight on silver bromide?
Sunlight triggers a chemical reaction in silver bromide, causing it to decompose into silver and bromine. This reaction is the basis for traditional black and white photography, where the exposed silver bromide in film or paper is converted into metallic silver to form an image.
