    and chemical properties of substances, which have special chemical symbols and can be represented by a chemical formula.

    2. Tap water refers to the water produced by the tap water treatment plant that meets the corresponding standards for people's life and production.

    3. Purified water refers to Ho without impurities, referred to as clean water or pure water, which is pure, clean, and does not contain impurities or bacteria, such as organic pollutants and inorganic salts.
