BTwo watermolecules interact to form a hydronium ion and a hydroxide ion. This is basically the definition of the process.

Answer: The correct answer is Option b.

Explanation:

Water is the compound which is formed by the covalent bonding of hydrogen and oxygen atoms. The chemical formula for this compound is \(H_2O\)

Self-ionization of water is defined as the process in which 2 water molecules react together to produce hydroxide ion and hydronium ion.

The equation for the self ionization of water molecule follows:

\(2H_2O(l)\rightarrow H_3O^+(aq.)+OH^-(aq,)\)

By Stoichiometry of the reaction:

2 moles of water molecules react together to produce 1 mole of hydronium ion and 1 mole of hydroxide ion.

Hence, the correct answer is Option b.
