En la electrosis del cloruro de sodio (Na Ci) el cloruro es atraido por elcatodo. Falso o verdadero. Y porque?
hram777 [196]

Answer:

Falso

Explanation:

La electrólisis es la descomposición de una solución cuando la corriente continua se pasa a través de ella.

La corriente entra y abandona el electrolito a través de los electrodos. El electrodo positivo se llama el ánodo mientras el electrodo negativo se llama cátodo.

Los iones positivos se mueven hacia el cátodo, mientras que los iones negativos se mueven hacia el ánodo.

Dado que el cloruro es un ion negativo, se mueve hacia el ánodo y no hacia el cátodo.
