Detailed explanation-1: -Bases can be defined as substances that produce hydroxide ions when dissolved in water (OH–). Acids and bases. An Arrhenius acid is any substance that ionizes when it dissolves in water to give the H+ or hydrogen. An Arrhenius base is any substance that gives the OH–, or hydroxide, an ion when it dissolves in water.
Detailed explanation-2: -Acids and Bases Hydroxide ions are produced under two conditions. First, they are produced when an ionic compound containing hydroxide such as sodium hydroxide dissolves in water. Second, hydroxide ions are produced when a substance like ammonia accepts a proton from water.
Detailed explanation-3: -Answer and Explanation: A base is an ionic compound that produces hydroxide ions when dissolved in water.
Detailed explanation-4: -(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.
