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.
A compound that does not dissolve in a particular solvent. For example, silver chloride is highly insoluble in water, calcium hydroxide is sparingly soluble in water and sodium chloride is insoluble in chloroform.
Why is tap water being used as a test substance
it is called insoluble

A small amount of insoluble residue remain.
This substance is insoluble in water.
oils are 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).
The insoluble white substance (precipitate) is silver chloride, AgCl, which is insoluble in water.
