Water's unique molecular structure and properties make it indispensable in chemistry. It acts as a universal solvent, dissolving a wide range of substances, and plays a pivotal role in acid-base chemistry due to its amphoteric nature. Water's ability to form hydrogen bonds contributes to its high boiling point and surface tension, and it is essential in processes like dissolution, hydration reactions, and hydrolysis, as seen in its interaction with chlorine.
