Exp. 8 lab report - Iodimetric titration of vitamin C

WebThe following equation shows the 1:1 reaction between Vitamin C (Ascorbic acid) and Iodine. C6H8O6 + I2 à C6H6O6 + 2I- + 2H+ Iodine (I2) solution is a brown solution and dissolved Iodide (I-) ions are colorless. Free iodine in the presence of starch makes an I2-Starch complex that is dark blue in color. If there is vitamin C, it will react with I2. Webcontrol contained no iodine, while our experimental group did, the independent variable was the iodine. Since the starch solution's color changed as a result of the iodine being placed in the water, the color of the starch solution after 24 hours must be the dependent variable, since it is being changed as a result of the independent variable. imagine jin wang\u0027s feeling traductionhttp://api.3m.com/testing+a+leaf+for+starch+lab+report list of feral animals in australia
