Hydrofluoric Acid（30%-70%）
Hydrofluoric Acid is an aqueous solution of hydrogen fluoride gas. It is a clear, colorless, smoky, corrosive liquid with a sharp, irritating odor. Hydrofluoric acid is a weak acid that is extremely corrosive and strongly corrodes metals, glass, and silica-containing objects. Can cause burns that are difficult to cure if inhaled by steam or contact with skin. It is usually made in laboratories with fluorite (the main ingredient is calcium fluoride) and concentrated sulfuric acid. It needs to be sealed in a plastic bottle and kept in a cool place.
