This method uses a back titration with potassium thiocyanate to determine the concentration of chloride ions in a solution.Before the titration an excess volume of a standardized silver nitrate solution is added to the solution containing chloride ions, forming a precipitate of silver chloride (AgCl). The term 'excess' is used as the moles of silver nitrate added are known to exceed the moles of sodium chloride present in the sample so that all the chloride ions present will react.Ag+ + Cl- AgCl(s) (Ksp = 1.70 × 10−10)Excess WhiteExcess of Ag+ is back titrated with SCN-.
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.
Nitrobenzene is added in volhard titration as an indicator to detect the endpoint of the titration between chloride ions and silver ions. It forms a red-brown complex with excess silver ions which marks the end point of the titration.
The purpose of Volhard titration is to determine the concentration of halide ions (such as chloride, bromide, or iodide) in a solution by titrating with a standardized silver nitrate solution. The endpoint of the titration is indicated by the formation of a colored precipitate of silver halide.
When silver nitrate reacts with sodium chloride, silver chloride is formed according to the equation: AgNO3 + NaCl -> AgCl + NaNO3. The molar ratio of silver nitrate to silver chloride is 1:1. Therefore, 100 g of silver nitrate will produce 143.32 g of silver chloride.
Argenmetric process
In the titration of silver nitrate solution, a precipitation indicator like chloride ion is used to detect the endpoint through the formation of a white precipitate (AgCl). An adsorption indicator like chromate ion can also be used, where the color change of the adsorbed chromate ion on silver chloride indicates the endpoint. Both indicators are effective in detecting the equivalence point in silver nitrate titrations.

Yes, a precipitation reaction will occur when sodium chloride is mixed with silver nitrate. The silver ions in the silver nitrate solution will react with the chloride ions in the sodium chloride solution to form insoluble silver chloride, which will precipitate out of the solution.

Because the product silver chloride is a white precipitate.

When an anion reacts with silver nitrate, a precipitation reaction can occur if the anion forms an insoluble salt with silver. For example, chloride ions react with silver nitrate to form silver chloride, which is a white precipitate. Other anions like bromide, iodide, and sulfide can also form insoluble salts with silver.
