After the addition of concentrated sulfuric acid (H₂SO₄) to wood, you may observe several reactions:Dehydration: The acid can remove water from the wood, leading to the charring or carbonization of the organic material. This often results in a blackened residue.Color Change: The wood may darken significantly due to the formation of carbon and other byproducts.Fume Production: Sulfuric acid can produce fumes, including sulfur dioxide (SO₂) and other gases, depending on the specific organic compounds present in the wood.Heat Generation: The reaction is exothermic, meaning it can produce heat.Overall, the wood will typically appear charred and may lose its structural integrity
