An environmental chemist is analyzing a water sample retrieved from an estuary to determine the mass of suspended clay particles. Before analyzing the dissolved ionic content, the insoluble clay must be separated from the saline solution.
Draw a labelled diagram of the gravity filtration apparatus used to separate the suspended clay to obtain a clear filtrate of the saline solution.
