Text Solution

AI Generated Solution

To determine which gas is evolved when formic acid is heated with concentrated sulfuric acid, we can follow these steps: ### Step 1: Identify the Reactants The reactants in this reaction are formic acid (HCOOH) and concentrated sulfuric acid (H₂SO₄). ### Step 2: Understand the Role of Concentrated Sulfuric Acid Concentrated sulfuric acid acts as a dehydrating agent. This means it can remove water (H₂O) from other substances during a chemical reaction. ...
