Question

Both iodometric and iodimetric titrations are carried out in:

• A. Basic medium
• B. Acidic medium
• C. Both acidic and basic medium
• D. Neutral medium

Answer 1

The correct option is B Acidic medium

Both iodometric and iodimetric titrations are carried out in acidic medium only as in basic medium, $I_2$ undergoes disproportionation reaction.
$I_2\left(g\right)+O{H}^{-}\left(aq\right)\to I^{-}\left(aq\right)+I{O}_3^{-}\left(aq\right)$
