AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding the Reaction Context**: In permanganate titrations, potassium permanganate (KMnO4) is commonly used as an oxidizing agent. The titration typically involves a reducing agent, such as oxalic acid (H2C2O4). 2. **Role of Hydrochloric Acid**: Hydrochloric acid (HCl) is often used to provide an acidic medium for the reaction. However, it is important to note that HCl is a strong acid. 3. **Reaction of HCl with KMnO4**: When KMnO4 is added to an acidic solution containing HCl, a side reaction occurs. The strong acid (HCl) can react with KMnO4, resulting in the formation of manganese(II) chloride (MnCl2) and potassium chloride (KCl), along with the release of chlorine gas (Cl2). ...
