Answer 2

The endpoint detection in the vol hard method involves​ fractional precipitation.

• Volhard's method involves indirect titration.
• In this method, there is the use of an excess silver nitrate solution which is added into chloride which contains the sample.
• There is the use of the standardized solution of potassium thiocyanate for the backward titration of silver ions.
• Ferric ion is used as the indicator in this process.
• This method is used for determining the anions present that precipitates the silver ions.
