Reaction of Alkyl Halides with Silver Nitrate - Chemistry ...

The silver nitrate test is sensitive enough to detect fairly small concentrations of halide ions. The mixture is acidified by adding dilute nitric acid. This prevents unreacted hydroxide ions reacting with the silver ions. Then silver nitrate solution is added. Various precipitates may be formed from the reaction between the silver and halide ions:

based upon silver nitrate are sometimes termed argentometric methods. Potassium chromate can serve as an end point indicator for the argentometric determination of chloride, bromide and cyanide ions by reacting with silver ions to form a brick-red silver ... saturating the analyte solution with sodium hydrogen carbonate.

Free Cyanide vs Total Cyanide Determination

Cyanide Titration with Silver Nitrate. The tests for free cyanide, total cyanide and hydrocyanic acid are made volumetrically, by slowly running silver nitrate solution from a burette into a known quantity of the cyanide solution. For this purpose a standard solution of silver nitrate is usually made up, of such a strength that the result may ...

Silver nitrate and Sodium chloride? | Yahoo Answers

Mar 26, 2009· Best Answer: I'm guessing you have been talking about precipitation reactions, so think about what might precipitate when these two substances are mixed together. In the two solutions you will have: AgNO3(aq) + NaCl(aq) When you combine those, the ions will recombine to give you Silver chloride and sodium nitrate.

metal - Why is silver nitrate used for cyanide titration ...

Or more to the point, since silver isn't exactly cheap: Why can't cuprous nitrate ($ce{CuNO3}$) substitute for the pricier ($ce{AgNO3}$) in cyanide titration? I assume that free cyanides bind eagerly with all Group 9-11 metals, since they're used industrially to leach the heavier ones.
