Okay, despite being a weak acid by the formal definition, hydrofluoric acid is extremely corrosive and dangerous because undissociated HF penetrates tissues and the fluoride ion strongly complexes with calcium and magnesium in the body. This is why HF can cause severe burns and systemic toxicity even though it is not a strong acid in the acid base sense.
That’s not the definition of a strong acid, a strong acid is an acid that protonates easily
It’s a weak acid
