Question

8. Which statement is not correct for argentometric titration
O O
Same amount of indicator must be used for blank correction and for titration of t
sample
O The pH of the solution must be 7-8 throughout the titration
The pH is not a factor here, because this is not an acid-base titration
O Blank correction can not be done with tap water​

Answer 2

The pH is not a factor here, because this is not acid-base titration is not correct for argentometric titration.

• Argentometric titrations use Ag+, also called precipitation reaction.
• These are of three types: Volhard Method, Mohr Method, and Fajans Method.
• these differ mostly in the use of the type of indicator.
• pH should be from 6-10
• pH influences titration as it depends on the type of anion and indicator used.
