    "abstract": "Formation and dynamics of an Al(OH)_3 precipitation ring is studied by\ndiffusing NaOH into a gel containing AlCl_3. Limited feeding of the outer\nelectrolyte (NaOH) is found to yield an intricate ring-dynamics which involves\nstopping and reversal of the direction of motion of the precipitation ring, and\nevolution into stationary multi-ring structures. A model of the ring-dynamics\nis developed by combining a phase separation scenario for the precipitation\nwith the redissolution (complex formation) of the precipitate in the excess of\nthe outer electrolyte.",
