What is the purest liquid in world?

The purest liquid in the world is often considered to be distilled water, as it is made through the process of distillation, which removes impurities and contaminants. However, in terms of chemical purity, ultra-pure water, used in laboratories, is even purer, containing minimal dissolved solids and impurities. Additionally, there are specialized high-purity solvents used in scientific research that can be considered among the purest liquids.
