Water's chemical stability is described by which term?

• A. Chemical Indestructibility
• B. Chemical Reactivity
• C. Chemical Instability
• D. Chemical Solubility

Answer: (A)

Chemical stability means a substance tends to keep its composition unchanged under ordinary conditions. Water is considered chemically stable because it does not break down or react readily in everyday environments, so it stays as H2O unless energy or a strong reactant drives a change. The term that best conveys this idea in the set is indestructibility, which suggests remaining intact and not undergoing chemical changes easily. In contrast, chemical reactivity describes how readily something reacts, chemical instability is the opposite of stability, and chemical solubility concerns how a substance dissolves in a solvent. So water’s tendency to remain unchanged under normal conditions fits the notion of indestructibility.
