Answer:
dissociation of water molecule to form hydrogen cations and hydroxide anions.
Explanation:
Dissociation refers to the process where molecules or compounds break apart into smaller particles, such as ions or radicals, often due to the interaction with a solvent or under certain conditions like temperature or pressure changes. This process can occur in various types of substances, including acids, bases, salts, and even some covalently bonded molecules like water.
