AgNO3 dissociates into Ag+ and NO3- ions in water and from these Ag+ions combine with Cl- in saline water (from ionised NaCl or CaCl2) to form the white AgCl precipitate.
So from the amount of AgNO3 consumed we can find Chloride content of water, which mostly correspondenses with salinity.
The nitrate ions are not reacting (all nitrates are/stay soluble, thus ionised)

ProfessorSilver nitrate is used to determine salinity through a process called the Mohr method. In this method, silver nitrate reacts with chloride ions in a solution to form a white precipitate of silver chloride. By titrating the silver nitrate solution with a potassium chromate indicator, the endpoint of the reaction can be visually detected, allowing for the determination of chloride concentration, which is directly related to salinity.

What happens when silver nitrate is titrated against potassium chloride?
When silver nitrate is titrated against potassium chloride, a white precipitate of silver chloride is formed due to the reaction between silver ions from silver nitrate and chloride ions from potassium chloride. This reaction can be used to determine the concentration of chloride ions in a solution.
Why is silver nitrate not used in electroplating silver?
Silver nitrate is a compound used for making silver salts, not for electroplating silver. In electroplating, a pure silver metal source is needed as the source of silver ions, not silver nitrate. This is because the ions in silver nitrate are not stable in solution for electroplating.
What is the effect of oxidizing agent on silver nitrate?
An oxidizing agent can react with silver nitrate by accepting electrons from the silver ion, reducing it to metallic silver. This reaction can lead to the formation of a different compound, depending on the specific oxidizing agent used. Additionally, the oxidizing agent's reduction potential will determine the extent to which the silver nitrate is reduced.
What is the molecular formula for silver nitrate?
The molecular formula for silver nitrate is AgNO3.
How could you react silver nitrate and copper?
When silver nitrate reacts with copper, a redox reaction occurs where the silver ions in the silver nitrate gain electrons from the copper atoms, resulting in the formation of silver metal and copper(II) nitrate. This reaction is often used as a test for the presence of halide ions, which form insoluble silver halides when reacted with silver nitrate.
