(Originais Teachy 2023) - Question Hard of Chemistry

An aqueous solution containing copper sulfate (CuSO4) and sodium chloride (NaCl) was prepared in the laboratory. To separate the two salts, a student proposed the following procedure: initially, perform filtration to remove the insoluble solid formed by the reaction of chloride ions with copper ions, and then evaporate the water to obtain the separated salts. Considering that the student has knowledge about the solubility of these compounds, critically describe the proposed procedure, identifying possible conceptual errors and suggesting alternatives for the correct separation of the salts. Additionally, explain how the use of solubility knowledge, which is a property of pure substances, can be related to the process of separating mixtures, which involves separating components of a mixture of substances.
