Question

Autoionization occurs when a neutral molecule ionizes into anion and a cation.

Which of the following equations best illustrates the autoionization of water?


Choose 1 answer:


(Choice A)


2H_2O⇌H_3O^++OH^-


(Choice B)


2H_3O⇌H^+_2+2OH^-


(Choice C)


2H_3O⇌2H_2O^++2OH^-


(Choice D)


2H_2O⇌H^+_2+O^-2H

Answer 1

A) Presence of hydrogens ion produced during reaction.

Answer 2

Choice A; because the autoionization chemical formula is 2H_2O – H_30^+ +OH^-
