In reality, yes, it is. Tap water contains dissolved minerals and gases. Certainly it is "clean" enough to drink, but there remain a number of dissolved elements and compounds that were not removed during processing. And there were a few things added, as well.
In tap water, you will most likely find iron. In distilled or deionized water, no.
A bean seed will likely grow faster in tap water because salt water and sugar water can inhibit germination and growth due to high levels of solutes. Tap water provides the ideal conditions for the seed to absorb water and nutrients necessary for growth.
Water moves out of the cell in hypertonic solution.
Using different kinds of water, such as tap water, distilled water, or rainwater, can impact the health of plants. Tap water may have minerals that could build up in the soil over time and affect plant growth. Distilled water lacks minerals that plants need for growth, while rainwater is usually the best option as it is natural and contains nutrients that plants can absorb easily.
Water moves from a hypotonic solution to a hypertonic solution.
Tap water is a solution because it is a homogenous mixture where the solute (dissolved substances) is evenly distributed in the solvent (water). Unlike colloids or suspensions, the particles in tap water are molecular in size and do not settle out over time.
When tap water and salt water are mixed together, the salt dissolves in the water and becomes part of the solution. The resulting solution will have a higher salt content than the original tap water.
Clean tap water is a homogeneous solution.
When silver nitrate is added to a tap water solution, it can form insoluble silver chloride precipitate due to a reaction with chloride ions present in the tap water. This precipitate appears as a white cloudy material, which causes the solution to change in appearance.

Unfiltered tap water is a pure substance
As long as its clean, clear tap water its a homogeneous mixture (since the various other things that are in the water exist only in solution).
If the solid substance is nonpolar, it will more likely dissolve better in an organic solvent rather than water. In this case, using distilled or tap water to prepare a solution may not make a significant difference in the solubility of the substance since it is nonpolar and not likely to dissolve well in water regardless.
Salt in a water solution will LOWER the Freezing Point of the resultant solution. Therefore the Saltwater will have to be cooled to a lower temperature. All other things being equal, that should take longer than the plain tap water.
Windex, bleach, tap water (which is NOT pure water, but has dissolved chemicals and minerals), vinegar, etc.
Tap water is generally considered a dilute solution because it primarily consists of water with a low concentration of dissolved substances, such as minerals, chlorine, and other contaminants. The concentration of these substances is typically low enough that it does not significantly alter the properties of the water. However, the exact concentration can vary depending on the source and treatment of the water.
