Cations typically act like which type of species?

• A. Lewis acids
• B. Lewis bases
• C. Bronsted-Lowry bases
• D. Arrhenius acids

Answer: (A)

Cations are electron pair acceptors, so they fit the Lewis acid role. The positive charge on a cation makes it electron-poor and eager to attract lone pairs from Lewis bases (like water, ammonia, or various ligands). This is the core idea behind Lewis acidity: an acid accepts an electron pair. Bronsted-Lowry bases would be proton acceptors, and Arrhenius acids are substances that increase H+ in solution; those definitions describe different aspects of acidity and do not capture why cations readily form coordination with electron donors. In short, the typical behavior of cations in solution aligns with Lewis acids.
