Short summary
Several studies using thermodynamic models estimated pH and sulfate formation rate during pollution periods in China are highly conflicting. Here we show distinct sulfate formation for organic seed particles from that of (NH4)2SO4 seeds, when the particles are exposed to SO2, NO2, and NH3 at high RH. Our results reveal that the pH value of ambient organics-dominated aerosols is sufficiently high to promote efficient SO2 oxidation by NO2 with NH3 neutralization under polluted conditions in China.
