Question

In the test for the presence of chloride, what is the purpose of initially adding nitric acid before the addition of the main reactant silver nitrate?


A.
The chloride ion needs to be surrounded with hydrogen ions (H+) to ensure that it is free to react with the silver ion of silver nitrate.


B.
This will neutralize any alkaline impurity what might react with the silver nitrate.


C.
The chloride ion needs to freely react with the silver ion of silver nitrate. Initially adding nitric acid will allow other ions present in the solution to react with the nitrate of nitric acid.


D.
This will lower the pH of the test solution.
