It is an indirect titration procedure for the determination of anions that precipitate with silver like CL-, Br-, I-, SCN-, and it is preferred in acid (HNO3) solution (because it prevents the harmful effects seen in other methods in which oxalate, arsenate and carbonate are used. Because these ions form silver salts with poor solubility, but in acidic mediums these salts are not formed). A measured excess of AgNO3 is added to precipitate the anion, and the excess of Ag+ is determined by back titration with standard potassium thiocyanate solution.

Why mohr method is better than volhard method?
because mohar method gives the accurate result
Why nitric acid is used in volhard method?
The titration must be done in acidic medium to prevent the precipitate of Iron(III) as hydrated oxide (iron hydroxide). Iron (III) is an indicator.
Why is an acidic titration medium a requirement of the vol hard?
volhard method uses Fe indicator. in the basic solution, Fe ion can precipitate forming Fe(OH)3 ...ete..
