Answer:
A. HYDROFLOURIC ACID
Explanation:
Solutions of HF are colourless, acidic and highly corrosive. It is commonly used to etch glass and silicon wafers. When hydrofluoric acid comes into contact with human skin it causes deep burns.In addition to being a highly corrosive liquid, hydrofluoric acid is also a powerful contact poison. Because of the ability of hydrofluoric acid to penetrate tissue, poisoning can occur readily through exposure of skin or eyes, or when inhaled or swallowed. Symptoms of exposure to hydrofluoric acid may not be immediately evident, and this can provide false reassurance to victims, causing them to delay medical treatment.
