What does silver nitrate detect?
Silver nitrate can be used to detect the presence of halide ions (chloride, bromide, iodide) in a solution by forming insoluble silver halide precipitates, which have distinct colors (white for chloride, cream for bromide, and yellow for iodide). It is commonly used in qualitative analysis to identify halide ions and in medical procedures such as the Schirmer's test for the detection of tear production.
Why is silver nitrate added to halide salts?
Silver nitrate is added to halide salts to test for the presence of halide ions. When silver nitrate is added, a precipitation reaction occurs where silver halide compounds are formed. The color of the precipitate that forms can help identify the type of halide ion present in the salt.
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
Why should you not expect the halides ions to dissolve in mineral oil?
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.
Silver nitrate is used for testing of which chemicals?
Silver nitrate is commonly used to test for the presence of halide ions, such as chloride, bromide, and iodide ions. When silver nitrate is added to a solution containing these ions, characteristic precipitates are formed: white for chloride ions, cream for bromide ions, and yellow for iodide ions.

What element has atoms that can form halide ions?
The element that can form halide ions is typically a halogen, such as chlorine, fluorine, bromine, or iodine. These elements have seven valence electrons and can gain one electron to achieve a stable electron configuration, resulting in the formation of negatively charged halide ions (e.g., Cl⁻, F⁻, Br⁻, I⁻). Halide ions are commonly encountered in various chemical compounds and reactions.

What are halogen ions called?
Ions of the halogen group are called halide ions; their compounds are called halides.
What are sodium hydroxide and copper sulfate used to test for?
Sodium hydroxide is used to test for the presence of metal ions like aluminum, calcium, and magnesium by forming white precipitates. Copper sulfate is used to test for the presence of halide ions like chloride, bromide, and iodide, producing colored precipitates.
What are all the possible oxidation states for the halide ions?
-1 oxidation state
Why silver nitrate is used in argentometric titration?
Silver nitrate is used in argentometric titrations because it forms insoluble silver chloride, silver bromide, or silver iodide precipitates with halide ions present in the solution. The endpoint of the titration is reached when all the halide ions have reacted with silver ions, forming a visible precipitate. This allows for precise determination of the halide ion concentration in the sample.
What is a halide leak detector test?
detect nytrogen
What is the word equation of photographic film?
The word equation for photographic film is: Silver halide crystals + light → Silver metal + halide ions.
