Why does salt dissolve in water?
ChemistrySolutions
Quick Answer
Salt dissolves because water molecules pull sodium and chloride ions apart and surround them. Water’s polarity makes it very good at separating ionic compounds.
The Full Story
Table salt is sodium chloride, an ionic compound made of positively charged sodium ions and negatively charged chloride ions. Water is a polar molecule, with a slightly negative oxygen end and slightly positive hydrogen ends. Those partial charges attract the ions and stabilize them in solution, allowing the crystal lattice to break apart. That is why salt dissolves readily in water but not in nonpolar liquids like oil.
