Jane wants to finish the reaction and collect the chalk precipitate. She uses the following method: Add 10 ml of calcium chloride (CaCl2) to 100 ml of Na2CO3 to a beaker. The mixture is stirred until a reaction producing a white precipitate is observed. The mixture is poured through a funnel with a filter paper insert. The beaker is rinsed with Na2CO3 to move all the precipitate into the funnel. The filter paper is air-dried on a watch glass.
