out the aregentometric titration (Moher method)? (1
marks)
Ans.
Neutral or weak basic solution
Always a solution of silver nitrate is
added to the solution of a halide
Basic Solution
Acidic solution​

Answer 1

Answer:

The Mohr titration should be carried out under conditions of pH 6.5 – 9. At higher pH silver ions may be removed by precipitation with hydroxide ions, and at low pH chromate ions may be removed by an acid-base reaction to form hydrogen chromate ions or dichromate ions, affecting the accuracy of the end point.
