It entirely depends on where the tap water is gotten. Mixture = two or more substances (which could be a single element or compound) PHYSICALLY mixed together. Q: air is not a mixture because of scientists freezing it and finding different liquids, it is a mixture because the compounds that make up air e.g. Distilled water is a compound because it contains only molecules of water . Depends. a mixture can be evenly or unevenly mixed. There is no water on the periodic table. Tap water is NOT a pure substance. It is not an element no matter where you get it. In some places, it's a mixture of water and various metals from the pipings, making it a mixture. Compound = two or more elements CHEMICALLY bonded to form a molecule or ionic compound. It contains both a mixture of solids liquids & gases ,and also it is a solvent . Tap water is a mixture because it contains certain amount of impurities in it due to which it conducts electricity whereas distilled water does not contain such… Tap water is somehow impure and we know that a mixture is chemically impure whereas pure water does not contains impurities so it is a compound So, tap water is a mixture. but most tap water is a colourless solution with small amounts of several ions dissolved in it. Just keep in mind the definition of a mixture and a compound. In some places, it runs through steel piping and becomes a compound commonly known as H20O4C. Tap water is a homogenous mixture or heterogeneous mixture Get the answers you need, now! If you can actually see solid particles in the water then yes it would be a mixture.
