In the balanced chemical reaction IO aI bH cH O dI -> a, b, c and d respectively, correspond to — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

We are interested to determine the coefficient ‘a’, ‘b’, ‘c’, and ‘d’. It is a redox reaction. We will balance each half-reaction separately and then add to get the final balanced reaction. Here, iodide ion I loses an electron to produce iodine gas 2I . The unbalanced reaction is written as follows - - 2 I I + e -> Multiply the iodide ion by 2 and electron by 2 such that two iodine ions combine to give one molecule of iodine gas and 2 electrons. The balanced reaction is written as follows, - - 2 2I I + 2e -> The oxidation half-reaction is written as follows, + - 3 2 2 IO + H e I + H O ->
