Water could be made
to boil at 105 degrees Celsius instead of 100 degrees Celsius by taking
the sample to a higher altitude. Pressure is directly proportional to
temperature. So when you bring water into higher altitude, you are increasing
the external pressure and therefore increase the boiling point.
The added KI does not have any impact
The reaction invovles Titration of vitaminc ( Ascorbic acid)
ascorbic acid + I₂ → 2 I⁻ + dehydroascorbic acid
the excess iodine is free reacts with the starch indicator, forming the blue-black starch-iodine complex.
This is the endpoint of the titration. since alreay excess KI is added ( the source of Iodine), it does not have an influence.
