There is such a thing as osmolar pressure. Simply put, water wants to dissolve things and it goes wherever the solute is. High enough concentrations of solute in the intestines cause actually cause water to leave body instead of being absorbed, often causing diarrhea. Oral rehydration solutions consist of water with appropriate amounts of sugar and salts such as sodium and potassium. There are very simple experiments you can perform to demonstrate this phenomena. Grab plants or something similar and put them inside three different solutions: hypertonic, isotonic and hypotonic. There will be interesting results. https://en.wikipedia.org/wiki/Osmotic_concentration https://en.wikipedia.org/wiki/Osmotic_pressure https://en.wikipedia.org/wiki/Osmosis |
