Commercial alcohol is denatured by adding copper sulfate to give it color and pyridine, a foul-smelling liquid. This process ensures the alcohol is unsuitable for consumption.
How is commercial alcohol rendered unfit for drinking, and what is the denaturation process involving copper sulfate and pyridine?

Commercial alcohol is rendered unfit for drinking through denaturation, where toxic or unpalatable substances are added to make it undrinkable. One denaturation process involves adding copper sulfate and pyridine. Copper sulfate imparts a blue color to the alcohol, serving as a visual deterrent. Pyridine, an aromatic compound, contributes a foul taste and smell, making the alcohol unpalatable. This denaturation process discourages the consumption of industrial or non-beverage alcohol, preventing its misuse. The addition of denaturing agents, like copper sulfate and pyridine, makes the alcohol unsuitable for consumption while retaining its usefulness for industrial and commercial purposes.
