Dear authors. I have the manuscript a final read a spotted a few minor things listed below.
I am somewhat concerned by the fraction of sources cited as “personal communications”. I would avoid those if at all possible and verify whether the material is already published by now.

Minor corrections:
L64: missing + sign after NH4
L74: remove strikethrough formatting from was
L109: 10pptv -> 10 pptv
L113: by Roberts et al., (Roberts et al., 2011) -> by Roberts et al. (2011)
L113: by Borduas et al., (2016) -> Borduas et al. (2016) [and numerous other similar replacements throughout the text]
L129: only at the pKas of the BH+, which are typically pH 9-10 -> only for BH+, which have pKa ranging from 9-10
L130: the sentence explaining pKa is unnecessary
L155: should H2O+H+ be replaced by H3O+ to make the reaction analogous to R1?
L164: (see for example (Afifi and Blatchley III, 2015) -> (see for example Afifi and Blatchley III (2015))
L166, L169: - should be superscript
L168: (see for example (Heller-Grossman et al., 1999) -> (see for example Heller-Grossman et al. (1999)) [and other similar replacements]
L190: are known … and so involve -> is known … and so involves
R6, R8: I would use H3O+ instead of H+
L210: remove strikethrough formatting from "at several"
L241: 10ppmv -> 10 ppmv [and other similar space insertions in other places in the text, e.g., L255]
L255: I would use cm3 instead of cc, here and elsewhere in the text
L267: unformatted reference here by Warneke
L367-377: please use correct arrows for the equilibrium reactions
L373: - should be superscript
L379: + should be superscript
L390: H -> Heff
L395: no need to provide formula of formic acid
410: no need to provide formula of ammonium sulfate
R11, R12, R13, R14, R15: please use correct arrows for the equilibrium reactions
L469: MIC is introduced without definition. I do not think there is need to for it, CH3NCO is not that much longer.
L638: please confirm that this formula should use the intrinsic (not effective) H
L642: velocity -> speed
L736: Never-the-less -> Nevertheless
L1158: + should be superscript
L1176: H -> Heff
L1180: remove comma
