* Neutralization Reaction: This is a reaction where an acid and a base react to form salt and water. The characteristic of neutralization is that the resulting solution is less acidic or basic, moving towards a neutral pH.
* Acids: Typically contain hydrogen (H+) ions and are often formed from non-metal elements like chlorine (HCl), sulfur (H₂SO₄), or phosphorus (H₃PO₄).
* Bases: Often contain hydroxide (OH-) ions and are frequently metal hydroxides like sodium hydroxide (NaOH) or potassium hydroxide (KOH).
So, while metals and non-metals are involved in many chemical reactions, they are not the primary reactants in a typical neutralization reaction. The primary reactants are the acids and bases.
