AI Generated Solution

To understand why HI cannot be obtained by heating KI with concentrated H2SO4, let's break down the process step by step: ### Step 1: Understanding the Reactants - **KI (Potassium Iodide)** is a salt that contains potassium ions (K⁺) and iodide ions (I⁻). - **Concentrated H2SO4 (Sulfuric Acid)** is a strong acid that also acts as an oxidizing agent. ### Step 2: Reaction of KI with H2SO4 When KI is heated with concentrated H2SO4, the expected reaction is: ...
