Pranam As far as I read it is like this on NaCl and it will not explode , catch fire etc. Salt (Sodium Chloride) does not catch fire in most circumstances because it requires extremely high temperatures to ignite. Any substance can catch fire if you make it hot enough. ... That's because Sodium and Chlorine are highly chemically reactive. When they form a bond, it releases a very large amount of energy. The salt itself doesn't explode, the molten salt is so hot that the water instantly boils to steam. As the water contacts the very hot molten salt it dissolves rapidly, transferring its heat to the water much faster than would happen if the salt did not dissolve. This dissolution after the chemical changes are described in the Chandogya Upanishad when explaining the Brahmam. "Place this salt in water, and then wait on me in the morning." The son did as he was commanded. The father said to him: "Bring me the salt, which you placed in the water last night." The son, having looked for it, found it not, for, of course, it was melted. The father said: "Taste it from the surface of the water. How is it?" The son replied: "It is salt." "Taste it from the middle. How is it?" The son replied: "It is salt." "Taste it from the bottom. How is it?" The son replied: "It is salt." The father said: "Throw it away and then wait. . .on me. He did so, but the salt exists forever. Then the father said: "Here also, in this body, . . . you do not perceive the Truth, my son; but there indeed it is. "That which is the subtle essence, in it all that exists has itself. It is the True. It is the Self, and you, Svetaketu, are it." KR IRS 22721
