Dear Authors,

Thank you for submitting your revised manuscript. You have largely addressed the major comments and questions from the referees. However, it seems that you have made very few and small revisions regarding the important series of questions from Referee 1 regarding the importance of pH in the chemistry you are studying and modeling. While you provide an often extensive response to the referee, few changes to the actual manuscript were made regarding this important topic. For example, it will not be clear to most readers that the pH was strongly buffered and likely did not change, or that you have reason to believe that most of the reactions and processes you are considering are not very pH dependent. Furthermore, a clear justification for the use of pH 7 buffer when cloud water is more acidic (pH 3-6) should be provided, along with a discussion of why you think it is reasonable to use a pH of 4 in the model while a pH of 7 was used in the experiments.

Best regards,
