Web25 de jan. de 2024 · One difference between a base and an alkali is that alkalis are ionic compounds that can break when dissolved in a polar protic solution, whereas bases can be either ionic or non-ionic. CuO, ZnO, and NH 3 are all covalent compounds that serve as bases. The ionic alkalis NaOH and KOH are crucial alkalis. Alkalis are all Arrhenius bases, ones which form hydroxide ions (OH ) when dissolved in water. Common properties of alkaline aqueous solutions include: • Moderately concentrated solutions (over 10 M) have a pH of 10 or greater. This means that they will turn phenolphthalein from colorless to pink. • Concentrated solutions are caustic (causing chemical burns).
