What would happen if you split battery acid on a car made of iron?

If battery acid were to spill on a car made of iron, it would likely cause corrosion and damage to the iron surface. Battery acid is typically sulfuric acid, which is highly corrosive and can react with iron to form iron sulfate and hydrogen gas. This reaction would lead to the deterioration of the iron car body, potentially causing structural weakness and aesthetic damage. It is important to handle battery acid carefully and avoid spills to prevent such damage.
