How to Calculate the Amount of Copper (II) Sulfate Pentahydrate

WebIn iodometry the starch is added only after the color due to triiodide has begun to fade, i.e., near the endpoint, because starch can be destroyed in the presence of excess triiodide. … WebJan 21, 2024 · Iodometric determination of copper is based on the oxidation of iodides to iodine by copper (II) ions, which get reduced to C u X +. The initial reaction, not the titration, is given as: 2 C u X 2 + + 4 I X − 2 C u I ( s) + I X 2 Then the titration reaction is: 2 S X 2 O X 3 X 2 − + I X 2 S X 4 O X 6 X 2 − + 2 I X − floating shelves next to hood
