. The enhanced reactivity of the particles is attributed to the presence of a layer of adsorbed water on the particle surface. This can be understood in terms of the increased hydrophilicity of calcium nitrate as compared to calcium carbonate. Role of ammonia chemistry and coarse mode aerosols in global climatological inorganic aerosol distributions. Geological Society, London, Special Publications. . The measured uptake coefficient accounting for the BET area of the sample is determined to be 2.5±0.1×10−4 for HNO3 on CaCO3 under dry conditions and is found to increase in the presence of water vapor.

Source apportionment of atmospheric aerosol in a marine dusty environment by ionic/composition mass balance (IMB). Data from experiments using a mass‐calibrated Knudsen cell reactor showed the stoichiometry for the reaction determined from gas‐phase species deviated from that expected from the balanced equation.

Competition between Displacement and Dissociation of a Strong Acid Compared to a Weak Acid Adsorbed on Silica Particle Surfaces: The Role of Adsorbed Water. It has been postulated that the reaction of nitric acid with calcium carbonate, namely, CaCO 3 (s) + 2HNO 3 (g) → Ca(NO 3 ) 2 (s) + CO 2 (g) + H 2 O(g), plays an important role in the atmosphere.

Transmission FTIR spectroscopy was used to probe both gas-phase and adsorbed products and showed that the reaction of HNO3 and CaCO3 is limited to the surface of the CaCO3 particle in the absence of adsorbed water.

A standard acid-base neutralisation reaction occurs (calcium carbonate is a basic mineral compound), with the carbonate mineral dissolving in the acid solution: 2hno3 + caco3 → ca (no3)2 + co2 +h2o You end up with an aqueous solution of calcium nitrate and carbon dioxide gas given off.
