Distilled water is a type of purified water that has undergone a process of distillation, which involves boiling water to produce steam and then condensing the steam back into liquid form. This process effectively removes impurities, minerals, and contaminants from the water, resulting in a highly pure form of H2O. Distilled water is commonly used in laboratories for experiments and testing where precise measurements and purity are essential. It is also used in medical settings for procedures that require sterile water, such as in dialysis machines and medical devices. Additionally, distilled water is preferred for certain industrial processes, such as in car batteries and steam irons, where mineral-free water is necessary to prevent corrosion or mineral buildup.
