Al colocar unos trocitos de zinc en un tubo de ensayo, agregamos 2 mL de acido clorhídrico. El Zinc sustituye el hidrogeno del a
Rudik [331]

Answer:

DICLORURO DE ZINC

Explanation:

La ecuación es:

Zn (s) + 2HCl (aq)  →  ZnCl₂ (aq) +H₂ (g)

El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.

Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).

Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:

- DICLORURO DE ZINC
