Question:
A student is asked to prepare 250.0 mL of 3.5 M copper (II) sulfate from solid copper (II) sulfate pentahydrate. Describe how this solution should be made in the chemistry laboratory.
Preparing Solutions in the Lab
Most chemical reactions that are performed in the lab are done in solution. This allows the reactants to mix and freely rotate and move, which speeds up reactions. Therefore many solutions are made in a chemistry lab. These solutions can be made using concentrated stock solutions or by dissolving a certain amount of solid in the solvent. The desired volume and concentration of a solution should be known before attempting to make it.
