A precipitation reaction can be driven by a gravity current that spreads on the bottom as a denser fluid is injected into an initially stagnant liquid. Supersaturation and nucleation are restricted to location where the two liquids come into contact, hence the flow pattern governs the spatial distribution of the final product. In this numerical study we quantitatively characterize the flow associated with the gravity current and distinguish three zones where the coupling of transport processes with reaction can take place depending on the time scales. A scaling law associated with the region of Rayleigh--Taylor instability behind the tip of the gravity current is also identified.
