In chemistry residue is whatever remains or acts as a contaminant after a given class of events. Residue may be the material remaining after a process of preparation, separation, or purification, such as distillation, evaporation, or filtration. It may also denote the undesired by-products of a chemical reaction.
The substance left after a flame test is typically a residue of the material that was burned. This residue can vary depending on the original substance and may contain remnants of unburned material, ash, or other byproducts of combustion.
The substance left in a dish after evaporation is known as the residue.
Residue is a substance that remains after a process such as cooking or chemical reactions. In a kid-friendly context, residue might refer to leftover food bits on dishes or utensils that need to be cleaned off.
A filtration residue is the solid substance left in the filter media(filter paper, sponge, activated charcoal, etc.)... Whenever filtration occurs when the solid substance is separated from the liquid the recovered liquid is called filtrate while the recovered solid is called residue or precipitate. It is sometimes associated with the residue left after decantaion but to be more specific some people call it filtration residue to clarify the statement.
After filtration, the resulting substance is the filtrate, which is the liquid or solution that has passed through the filter, leaving behind any solid particles or impurities. The filtrate is usually collected in a separate container from the residue that is left on the filter.

The black substance is likely to be the residue of the substance that was heated in the evaporating dish. This residue is left behind after the solvent or liquid has evaporated, and can be carbon or other impurities from the original substance. It is important to clean the evaporating dish thoroughly to remove the residue before its next use.
Residue, or perhaps filtrate.
The formula for the solid residue remaining after evaporation depends on the substance that was evaporated. In general, it can be represented as the original substance's chemical formula followed by the word "residue" to indicate that it is the remaining solid after evaporation.

Ammonium nitrate leaves no residue when heated:NH4NO3 Δ→ N2O + 2H2O
The substance left behind in the bottom of an evaporating dish after the solvent has evaporated is called the residue. This residue is what remains of the dissolved solute once the solvent has been removed through evaporation.

A small amount of insoluble residue remain.
Solid residue is the leftover material that remains after a substance has been burned, processed, or filtered. It typically consists of any impurities, unburned material, or byproducts that were not fully consumed in the process.
