To remove the remaining powdered malachite from the solution, we need to use the process of filtration. We can set up a simple filtration apparatus using a filter paper and a funnel. Place the funnel on top of a beaker and fold the filter paper such that it fits inside the funnel. Pour the malachite solution through the filter paper and funnel. The filter paper will trap the powdered malachite and the clear solution will pass through and collect in the beaker. We can then carefully dispose of the used filter paper and the trapped powdered malachite.
