Tīmeklis2024. gada 12. apr. · The rate law expression for the reaction was rate=k [FeCl 3] 1 [KI] 0, which was equivalent to rate=k [FeCl3] 1. Calculating rate constant from the data was possible because the order of the reaction and the concentrations of the reactants were known. The rate constant was calculated by substituting the rate of one of the runs … Tīmeklis2013. gada 18. apr. · FeCl3与KI的反应方程式及现象. #热议# 个人养老金适合哪些人投资？. 碘离子会被三价铁离子氧化成碘单质，而碘在水中溶解度较小，所以应该会有沉淀 … humane society of granville county nc

Tīmeklis2011. gada 2. jūn. · When the amount of H2O was increased, the transmittance would decrease at a slower rate. In trial five, when no water was present, the transmittance level was at it's lowest. When the reactants were increased (KI or FeCl3), it pushed the chemical reaction to the right, causing more products to form.Thus, when products … TīmeklisFeCl3与KI的反应方程式及现象. 扫码下载作业帮. 搜索答疑一搜即得. 答案解析. 查看更多优质解析. 解答一. 举报. 2FeCl3+2KIKI3. 第一步反应,碘离子被氧化成单质. 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. humane society of greater dayton
