Detailed explanation-1: -(b) In aqueous solution, a base dissociates into hydroxyl ions (OH–) and cations. Every molecule of a strong base dissociates, producing a high concentration of OH–. When an acid and a base react (combine) releasing equal quantities of H+ ions and OH-ions, neutralization results.

Detailed explanation-2: -Bases react with water by accepting an H+ ion from a water molecule to form the OH-ion.

Detailed explanation-3: -OH− is a diatomic anion with the chemical name Hydroxide. Hydroxide is also called Hydroxyl or Hydroxyl radical or hydroxide ion. It consists of hydrogen and an oxygen atom which are held together by a covalent bond. The hydrogen carries a negative electric charge.

Detailed explanation-4: -OH-is called a hydroxyl ion and it makes things basic. However, in water, there is a balance between hydroniums and hydroxyls so they cancel each others’ charges. Pure water is neither acidic or basic; it is neutral.

Detailed explanation-5: -An Arrhenius base is a substance that dissociates in water to form hydroxide (OH–) ions.
