摘要在25°C下测量了甲磺酸（MSA）的分压，并用于估算反应的平衡常数为6.5×1013 mol 2 kg-2 atm-1：CH 3SO 3 H（g）= H+（aq）+CH 3SO 3-（aq）。MSA将被大气中的水有效地清除。作为一种强酸性物质，MSA会置换海洋气溶胶中的HCl气体，并可能是远程大气中HCl（g）的一部分。
Abstract The partial pressure of methanesulphonic acid (MSA) was measured above concentrated aqueous MSA solutions at 25°C and used to estimate an equilibrium constant of 6.5×1013 mol2 kg‐2 atm‐1 for the reaction: CH3SO3H(g) = H+(aq)+CH3SO3 ‐(aq). MSA will be effectively scavenged by water in the atmosphere. As a strong acid MSA will displace HCl gas from the marine aerosol and may be responsible for a part of HCl(g) in the remote atmosphere.
