Calcium carbonate is an insoluble solid. Calcium carbonate can be made by adding excess aqueous calcium chloride to aqueous sodium carbonate. $$\[ \mathrm{CaCl}_{2}(\mathrm{aq})+\mathrm{Na}_{2} \mathrm{CO}_{3}(\mathrm{aq}) \rightarrow \mathrm{CaCO}_{3}(\mathrm{~s})+2 \mathrm{NaCl}(\mathrm{aq}) \]$$ A student makes a sample of calcium carbonate. The first two steps of the method are shown in Fig. 1.1. Fig. 1.1 After step 2 the student filters the mixture to remove the solid calcium carbonate formed and collect the filtrate. Draw a labelled diagram to show the apparatus used for this filtration.
