Many substances are insoluble in tap water, but one common example is oil. Due to its nonpolar nature, oil does not mix with the polar molecules in water, causing it to separate and remain undissolved. Other examples include certain salts and minerals, such as barium sulfate and silver chloride, which also do not dissolve in tap water.
oils are insoluble in water
Normal tap water can be considered as fairly pure and homogeneous; only ultrapure water is correctly pure. Sometimes tap water may contain insoluble impurities.
When a substance does not dissolve in water, it is called insoluble. This means that the substance does not break apart and mix uniformly with water to form a solution.
Why is tap water being used as a test substance
Insoluble refers to a substance that does not dissolve in a particular solvent, typically water. These substances tend to remain in a solid state when added to the solvent and do not form a homogenous mixture. Examples of insoluble compounds include certain minerals like sand and graphite.

A small amount of insoluble residue remain.
This substance is insoluble in water.

A substance is soluble with another substance if it can be dissolved into it. solubility is defined with respect to another substance (usually water) eg) salt is soluble in water. oil is insoluble in water.
by heating the mixture so the water will evaporate and the insoluble substance will remain
Any non-polar substance will not dissolve in water (insoluble).
Why is tap water being used as a test substance
Tap water is a mixture becasue of the differnet chemicals in water.
A substance that does not dissolve is insoluble.
