Short summary
The heterogeneous loss of dinitrogen pentoxide (N2O5) to citric acid aerosol, a proxy for highly oxygenated secondary organic aerosol, is shown to be substantially lower than to other aqueous organic aerosol proxies investigated previously. This is attributed to the widely changing viscosity within the atmospherically relevant humidity range. It may explain some of the unexpectedly low loss rates of N2O5 to aerosol particles derived from field studies.
