<jats:title>Abstract</jats:title> <jats:p>The solubilities of methylmercury(II) chloride (MMC), methylmercury(II) bromide (MMB), methylmercury(II) iodide (MMI), ethylmercury(II) chloride (EMC), and ethylmercury(II) bromide (EMB) in water have been determined over the temperature range of 10–55 °C (20–40 °C for MMC and EMC). The temperature dependence of the solubilities expressed as mole fractions x2 was given by the following equations:</jats:p> <jats:p>& logx_2(MMC)=-1059/T+0.176 (20–40°C)</jats:p> <jats:p>& logx_2(MMB)=-1094/T-0.263 (10–55°C)</jats:p> <jats:p>& logx_2(MMI)=-463/T-3.246 (10–25°C)</jats:p> <jats:p>& logx_2(MMI)=5.498×10^6(1/T)^2-3.711×10^4(1/T)+57.814 (25–55°C)</jats:p> <jats:p>& logx_2(EMC)=-1048/T-0.612 (20–40°C)</jats:p> <jats:p>& logx_2(EMB)=-179/T-4.293 (10–25°C)</jats:p> <jats:p>& logx_2(EMB)=5.389×10^6(1/T)^2-3.603×10^4(1/T)+55.322 (25–55°C)</jats:p> <jats:p>The thermodynamic parameters for the transfer process from solid to saturated aqueous solution were also determined.</jats:p>
