How Do You Explain How Salt Effects The Temp At Which Water Boils Using The Particle Theory?
Salt ionizes when it dissolves, breaking up into Na+ and Cl- ions. THose ions are surrounded by water molecules, with the water molecules’ dipoles being aligned according to the charge of the ion. The oxygen, with its partial negative charge, will be closer to the Na+ ions. For the Cl-, the hydrogens, with their partial positive charge, will be closer. The interaction of the water molecules with the ions, the attraction thereof, makes the water molecules less likely to fly off to be vapor; not only do they have to overcome the attraction to other water molecules, but also the attraction to the ions.
