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.
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.
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).
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.
Chalk is made of calcium carbonate, which is slightly soluble in water due to its ionization into calcium and carbonate ions. When chalk is exposed to tap water, the water molecules break down the chemical bonds in the chalk, causing it to dissolve and form a solution.
Solutes and solvents. A simple solution is basically two substances that are evenly mixed together. A solute is the substance to be dissolved (for instance salt). The solvent is the one doing the dissolving (for example water).
A concentrated solution contains a single component (or very very nearly so). A dilute solution contains a large quantity of "contaminant". For instance, a glass of tap water is (for the purpose of this explanation) concentrated H2O. Now take this glass of water, and pour it into a bowl, and fill the bowl with bleach. Now the bowl is roughly 75% bleach, and 25% water, which is a dilute solution of water. Removing the water would produce a concentrated solution of bleach and vice versa.
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.
A clear liquid with a pH of 8 is alkaline in nature. It is slightly basic and can commonly be found in products like soapy water or baking soda solutions.
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.

The concentration of sugar in tap water is "pretty much zero," while the concentration of sugar in something called "sugar water" is presumably "above zero". Which of those soundshigher?
No, pouring tap water into your urine will not cover up a drug test. Drug tests are designed to detect specific substances in urine, and adding water will dilute the sample but is likely to be detected by the testing process.

You can't dilute urine, because the only thing you'd have to dilute it with is tap water, and that would show up on the urinalysis. Urine does not contain H2O. It's been chemically changed by the time it comes out as urine.
