1) Como bien han respondido ya, el sulfúrico puede llegar a calcinar bastante. Podría dejar un cadáver irreconocible pero no hacerlo desaparecer por completo
2) Gato con cosas peores me refería sobre todo a la salud. ¿Qué es peor que colocarte con un disolvente orgánicao sin querer? Colocarte y saber que es un carcinógeno demostrado...
3) Si hay un ácido realmente peligroso es el fluorhídrico (HF). Citando a la wikipedia que está en inglés y acojona más:
"Symptoms of skin exposure to dilute HF are not felt immediately, but exposure of less than 10% of the body to it can be fatal, even with immediate medical treatment. Highly concentrated solutions may lead to acute hypocalcemia, followed by cardiac arrest and death, and will usually be fatal in as little as 2% body exposure (about the size of the sole of the foot). This substance is extremely toxic and has the capacity to kill upon exposure rather than simply damage skin and eyes. It should be handled with extreme care, beyond that given to hydrochloric, sulfuric, or other mineral acids.
Due to low dissociation constant, HF can penetrate tissues quickly like a small non-polar particle. Hydrofluoric acid which comes into direct contact with the fingers can severely damage or destroy the tissue underneath the nail without causing any damage to the nail itself. It is this ability to cause little harm to outer tissues but considerable harm to inner tissues which can produce dangerous delays in treatment of hydrofluoric acid exposure. Once the pain starts, it is out of proportion to the burns produced. Patients often describe the feeling as if they have struck their fingers with a hammer. HF that penetrates under the skin causes later development of painful ulcers, which heal slowly.
Solutions of less than 20% HF can produce pain and redness with delay up to 24 hours after skin exposure. 20 to 50% HF produces pain and redness within 8 hours, and solutions of more than 50% produce immediate burning, redness and blister formation. Contact of the skin with the anhydrous liquid produces severe burns. Calcium gluconate is used to treat hydrofluoric acid exposure Calcium gluconate is used to treat hydrofluoric acid exposure
In the body, hydrofluoric acid reacts with the ubiquitous ions of calcium and magnesium and so can disable tissues and organs whose proper function depends on these metal ions. Exposure to hydrofluoric acid may not be initially painful, and symptoms may not occur until several hours later, when the acid begins to react with calcium in the bones. Under most circumstances, hydrofluoric acid exposure results in severe or even lethal damage to the heart, liver, kidneys, and nerves. Initial treatment to hydrofluoric acid exposure usually involves applying calcium gluconate gel to the exposed areas. If exposure is high, or too much time has passed, a calcium gluconate solution may be injected directly into a local artery or surrounding tissues. In all cases, hydrofluoric acid exposure requires immediate professional medical attention. If coming in contact with human skin or bone the acid can severely burn and then decompose the bone, potentially necessitating amputation of the affected"
Y si vais al artículo así sigue la cosa. En química prácticamante no se utiliza. Los orgánicos suelen preferir nBu4NF (fluoruro de tetrabutilamonio). Suele utilizarse más en geología para atacar silicatos (el enlace Si-F es muy fuerte y rompe el enlace Si-O; en orgánica la aplicación es similar, romper éteres de silicio).
Al menos recuerdo dos muertes por HF. Si me memoria no me falla una chica francesa estaba sentada trabajando con una cubeta de HF y se la derramó sobre las piernas. También he conocido algunos sustos por culpa de frascos rotos.
4) Según el protocolo de seguridad las batas deberían ser 100 % algodón, al parecer, en caso de prenderte fuego, ardería más lentamente. En la práctica la mayor parte de ellas (incluída la mía), tienen más poliéster que algodón
5) ¿Me he dejado alguna respuesta? Si es así perdonad y hacedmelo saber
