Question

When water dissociates, each water molecule splits into a hydroxide ion and ______. A) H 3 O + B) a hydrogen atom C) a hydrogen ion D) H 2 O E) OH —

Answer 1

Answer: The correct answer is Option C.

Explanation:

Water is a molecule which is formed by the combination of hydrogen and oxygen atoms. The chemical formula for this is $H_2O$

Ionization is a special type of dissociation process. It is defined as the process in which a molecules splits into its ions.

When water dissociates, it leads to the formation of 2 ions, which are hydroxide ion and hydrogen ion.

The chemical equation for ionization or dissociation of water molecule is:

$H_2O(l)\rightarrow H^+(aq.)+OH^-(aq.)$

Hence, the correct answer is Option C.
