In a chem lab, why do I have to use ethanol and distilled water to rinse solid copper that I will have filtered from a solution of zinc chloride and zinc sulfate?
Can you explain to me why we need to use ethanol and distilled water to rinse solid copper in a chem lab?
Certainly! Ethanol and distilled water are used because they are both polar solvents, which means they can dissolve and remove any remaining impurities from the copper. This is important because any impurities on the surface of the copper can affect subsequent reactions or experiments.
