If you need to use powdered copper sulfate in an experiment and we're only supplied with clumps of copper sulfate which tool would you need to convert the copper sulfate to usable form?

You would need a mortar and pestle to crush and grind the clumps of copper sulfate into a fine powder for use in your experiment. This tool will help you break down the clumps into smaller particles, making the copper sulfate easier to dissolve or mix with other substances.
