KINETIC STUDY OF THE REACTION OF KI WITH FeCl3 (Revised: 5-20-96) INTRODUCTION Concentration of reactants is one factor which influences the rate of a chemical reaction. The following reaction will be investigated: 2 I-(aq) + 2 Fe3+(aq) ─────────> I 2(aq) + 2 Fe 2+(aq)

Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a FeCl3 + b KI = c FeCl2 + d KCl + f I2. Create an equation for each element (Fe, Cl, K, I) where each term represents the number of atoms of the element in each reactant or product.

KI is a reducing agent (i.e. it lost electrons) and FeCl 3 is a oxidizing agent (i.e. it gained electrons). Balance FeCl3 + KI = FeCl2 + I2 + KCl and find the reducing and oxidizing agents.

Phản ứng KI + FeCl 3 hay KI ra I 2 hoặc KI ra KCl hoặc FeCl 3 ra FeCl 2 hoặc FeCl 3 ra KCl thuộc loại phản ứng oxi hóa khử đã được cân bằng chính xác và chi tiết nhất. Bên cạnh đó là một số bài tập có liên quan về KI có lời giải, mời các bạn đón xem:

1 KI + 1 FeCl 3 = 1 I 2 + 1 KFeCl 3 对于每个元素，我们检查方程两边的原子数量是否平衡。 K 已平衡: 试剂中有 1 个原子，产物中有 1 个原子。 I 不平衡: 试剂中有 1 个原子，产物中有 2 个原子。 为了平衡双方的I，我们： 将 KI 的系数乘以 2 2 KI + 1 FeCl 3 = 1 I 2 + 1 KFeCl 3

2 FeCl3 + 2 KI → 2 FeCl2 + I2 + 2 KCl - Balanced equation | Chemical Equations online! This is an oxidation-reduction (redox) reaction: KI is a reducing agent, FeCl3 is an oxidizing agent. Appearance: Bluish black or dark purple crystals with pungent odour ; Violet solid with a sharp, characteristic odor.

A. 三价铁离子能把碘离子氧化为单质碘,2Fe3++2I−⇌2Fe2++I2,即FeCl3与KI发生了氧化还原反应,有I2生成，故A正确；B. 2mL0.1mol/LKI溶液于试管中,滴加0.1mol/LFeCl3溶液3滴,KI过量,溶液中滴加KSCN溶液,变红色,说明溶液中存在铁离子,则FeCl3与KI的反应具有可逆性，故B正确；C. 用 ...
