The solid left on the filter paper during filtration.

The insoluble solid left on the filter paper after filtration.

The solid left on the paper is the residue; the liquid collected below is the filtrate.

The insoluble solid left on filter paper during filtration.

Identify the substances at filtration: copper(II) oxide is the residue; copper(II) sulfate solution is the filtrate.

The copper sulfate is in the filtrate, not the residue: dissolved salts pass through filter paper.

In this preparation, keep the residue on the filter paper. The desired salt is insoluble.
