Gray-Weale and Beattie's rationalization of the negative charge observed on the surface of water in terms of accumulation of OH(-) is based on the supposedly uniquely large dielectric decrement of hydroxide solutions [A. Gray-Weale and J. K. Beattie, Phys. Chem. Chem. Phys., 2009, 11, 10994]. We challenge this rationalization and point to another ion, namely fluoride, which has a comparable dielectric decrement and size and which is repelled from the surface of water.
格雷-威利斯和贝蒂用 OH(-) 的积累来解释水表面观察到的负电荷，这是基于氢氧化物溶液具有据称是独特的大介电损耗这一假设[A. Gray-Weale 和 J. K. Beattie, Phys. Chem. Chem. Phys., 2009, 11, 10994]。我们对这一解释提出质疑，并指出另一种离子，即氟离子，它具有相当的介电损耗和大小，并且被排斥在水的表面之外。
