Document Summary
Solutions are mixtures in which atoms and molecules intermingle on the molecular and atomic scale. Thirsty solutions: why you should not drink seawater. Drinking seawater causes dehydration because seawater draws water out of body tissues. Draws water as it passes through stomach and intestine, resulting in diarrhea and further dehydration. Seawater is a thirsty solution, one that draws more water to itself. Seawater is a solution, homogeneous mixture of two or more substances or components. In seawater, water is solvent and sodium chloride is main solute. Seawater draws water to itself due to nature"s tendency toward spontaneous mixing. Substances tend to combine into uniform mixtures, not separate into pure substances, unless it is highly unfavourable energetically. Substances spontaneously mix together to form a more dilute solution of uniform concentration. Fluids in the body are more dilute than seawater. Body fluid becomes more dilute and solution in the cell becomes more concentrated. Accumulation of extra fluid in intestines causes diarrhea.
