Corrosive fluid is a term used to describe a type of liquid that has the ability to corrode or dissolve other materials. The most common type of corrosive fluid is ACID, which is a four-letter word. Acids are typically composed of hydrogen and one or more other elements, such as oxygen, chlorine, sulfur, or nitrogen. They are often found in nature, but can also be produced synthetically. Acids are highly corrosive and can cause damage to organic and inorganic materials, including metals, plastics, and fabrics.
