The errors that can occur in iodometric titration?

In iodometric titration, common errors can arise from improper preparation of solutions, such as inaccurate concentrations of iodine or thiOSulfate. Environmental factors, like light exposure, can lead to the degradation of iodine, affecting the results. Additionally, incomplete reactions or misreading the endpoint can introduce significant inaccuracies. Lastly, contamination of reagents or apparatus can alter the concentration of reactants, further complicating the titration results.
