The correct answer is: B. making it unsuitable for drinking.
Denaturation of ethanol is the process of adding other chemicals to ethanol to make it undrinkable. This is done for a number of reasons, including:
- To prevent people from drinking it and getting alcohol poisoning.
- To make it unsuitable for use in alcoholic beverages.
- To make it suitable for other purposes, such as industrial use or fuel.
The most common way to denature ethanol is to add methanol, which is a poisonous substance. Other chemicals that can be used to denature ethanol include pyridine, benzene, and isopropyl alcohol.
Denatured ethanol is often used in industrial processes, such as in the production of fuel and solvents. It can also be used as a disinfectant and as a fuel additive.
It is important to note that denatured ethanol is not safe to drink. If you consume denatured ethanol, you could experience a number of health problems, including alcohol poisoning, blindness, and death.
If you are concerned that you or someone you know has consumed denatured ethanol, it is important to seek medical help immediately.
