(离子在水中的溶剂化对许多生物过程至关重要。)
“Strong solvation effects can significantly alter the reactivity of molecules.”
(强烈的溶剂化效应会显著改变分子的反应活性。)
solvation energy — 溶剂化能,指溶质从气相转入溶液时释放或吸收的能量,用于衡量溶剂化过程的强度。
“The solvation energy of sodium chloride in water is highly negative.”
(氯化钠在水中的溶剂化能具有很高的负值。)
solvation shell — 溶剂化层,指直接围绕溶质分子排列的溶剂分子层,影响溶质的化学性质。
