A corrosive solution is a liquid that can cause chemical burns or other damage to living tissue. The term can refer to both ACIDS and bases, such as the four letter word ACID and the three letter word LYE. ACIDS are substances that have a pH lower than 7, while bases have a pH higher than 7. ACIDS are often used in industrial processes, such as the five letter word ACIDS, which are compounds that contain hydrogen and can react with other substances.
