Strong Acid: A strong acid is one that completely ionizes or dissociates in water, releasing all of its hydrogen ions. Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
Dissociation: The process by which an ionic compound breaks apart into separate ions when dissolved in water. In the case of nitric acid, it dissociates into H+ and NO3- ions.
Corrosive: Referring to substances that can cause damage or destruction to materials through chemical reactions. Nitric acid's corrosive nature stems from its ability to react strongly with many substances, including metals and organic matter.
