Primarygun Posted September 24, 2006 Share Posted September 24, 2006 In iodometric titration, why do we add the starch solution when it is close to the end point instead of pouring it at first? Link to comment Share on other sites More sharing options...
Borek Posted September 24, 2006 Share Posted September 24, 2006 If there is a lot of iodine it forms a stable compound with starch. When there are small amounts of iodine, reaction is reversible.
