Corrosivity describes a material’s capacity to damage or destroy other substances through a chemical reaction on contact. It refers to the destructive attack a chemical can have on materials—metals, skin, or other surfaces—via processes like oxidation or dissolution. This is what makes acids and strong bases capable of corroding metals or tissue. Reactivity is related but broader, indicating a substance can undergo a chemical change, not necessarily causing destructive damage on contact. Toxicity pertains to harm to living organisms, and solubility is about how well a substance dissolves in a solvent. So corrosivity is the term that best fits the description of causing damage upon contact through chemical reaction.
