http://ru.solverbook.com/question/fecl3-ki-uravnenie-reakcii/ Tīmeklisa: Add KI to FeCl3 solution (Note that I^(-) ad Fe^(3+) are the active species; K^(+) and Cl^(-) are spectator ions) b The oxidation of the I^(-) to I2 in the above reaction can be shown more clearly by adding starch solution. To FeCl3 add 10 drops of starch solution. Now add KI. c Now to the resulting solution add dropwise NaOH. TīmeklisWhat is the order of the reaction in FeCl3 and KI? Explain. 1st. The reaction should be dependent on [I-] with a first-order relationship and not be dependent on the concentration of [FeCl 3]. 3.
