An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water. Arrhenius acids include compounds such as HCl, HCN, and H2SO4 that ionize in water to give the H+ ion. Arrhenius bases include ionic compounds that contain the OH- ion, such as NaOH, KOH, and Ca(OH)2.

How is oh ion formed?
Hydroxide is a diatomic anion with chemical formula OHu2212. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge.

What are 5 examples of base?
What are 5 examples of bases? Some common strong Arrhenius bases include Potassium hydroxide (KOH), Sodium hydroxide (NaOH), Caesium hydroxide (CsOH), Strontium hydroxide (Sr(OH)2), and Lithium hydroxide (LiOH).
How is a base produced?
Usually, these bases are created by adding pure alkali metals such as sodium into the conjugate acid. They are called superbases, and it is impossible to keep them in aqueous solutions because they are stronger bases than the hydroxide ion. Therefore, they deprotonate hydronium ion, conjugate acid of water.
What is the catalyst used in the reaction?
Summary. A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.
