The hydroxyl radical (OH) plays a crucial role in the chemistry of the atmosphere as it initiates the removal of most trace gases. A number of field campaigns have observed the presence of a "missing" OH sink in a variety of regions acro... V Ferracci,I Heimann,NL Abraham,... - 《...
When an aqueous ion is listed as having a negative entropy value, it means that the ion is imposing order on its surroundings, thereby decreasing the entropy. For solvated ions, this can be thought of as an ion's solvation shell. The water molecules become more ordered around the solvated ...
