Normal tap water can be considered as fairly pure and homogeneous; only ultrapure water is correctly pure. Sometimes tap water may contain insoluble impurities.
Unfiltered tap water is a pure substance
Tap water is a homogeneous mixture, which means it has a uniform composition throughout. It is a mixture of water molecules along with dissolved minerals, gases, and other compounds, but these components are evenly distributed.
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
Tap water is a mixture of water (H2O) and minerals used to purify it.
Tap water is not a pure substance. Water has particles in it. Some tap water also contains fluoride. Distilled water has all of the particles taken out of it and is considered pure water.
One could say that water, if it comes directly out of the tap, or has minerals added for bottled water, that it is a homogeneous mixture. However, pure water is a pure substance, not a mixture. Italian dressing has at least two obvious components: vinegar on the bottom and oil on top, which is why it needs to be shaken. Mouthwash is definitely a homogeneous mixture of the substances listed in its ingredients.
Tap water is not a pure substance because it is mixed with chemicals that purify it and if it was from the ground it has naturally occurring minerals mixed in it.
No, tap water is not naturally blue. If tap water appears blue, it may have been artificially colored or contaminated by substances such as copper or other minerals. A homogeneous mixture is a uniform mixture where components are evenly distributed, but colored tap water would not be considered a homogeneous mixture as it is not naturally occurring.
City tap water contains many substances dissolved in it. So city tap water is a mixture. Different types of gasses, substances can be dissolved in this water.
Tap water is not a pure substance because it is mixed with chemicals that purify it and if it was from the ground it has naturally occurring minerals mixed in it.
Tap water is a mixture because it contains various substances dissolved or suspended in it, such as minerals, gases, and other compounds. It is not a pure chemical substance because it is composed of multiple components.
