Why does salt have a melting point 800c, but it dissolves in water so easily
In: Chemistry
The high melting point is because of its cristalline structure: the more tightly and strongly packed the molecules, the higher the melting point because it takes more energy to pull them loose. However, salts are made of ions, which are atoms with opposite electric charges, and water also has a separation of charges because of the characteristics of the atoms of hydrogen and oxygen: if you rub a pen with a cloth and put it beside a stream of water from your tap the stream bends. Because of this separation of charges water can dissolve salts so easily, oil for example cannot.
