Question

Antifreeze is 96 percent:

Buffering material

Corrosion inhibitor

Friction modifier

Ethylene glycol

Answer 1

Antifreeze is typically made of a key ingredient known as **ethylene glycol**, which is often mixed with water and may include other additives such as corrosion inhibitors, friction modifiers, and buffering materials. However, the statement "Antifreeze is 96 percent" is likely referring to the concentration of ethylene glycol in a specific formulation of antifreeze.

So, from the provided options, the correct identification would be:

- **Ethylene glycol** (as it's the primary component that antifreeze is based on, often at high concentrations).

If you're asking about the composition of a specific antifreeze product, it might contain 96 percent ethylene glycol, but it can also include various additives to improve performance and protection in a vehicle's cooling system.
