Scientifically, can salt lose its saltiness? If yes, how does it lose its saltiness?

Answer 1

I assume you mean regular table salt, NaCl. Table salt will remain table salt unless it reacts with something else. It will not break down, get old or loose its saltiness.

If it gets wet then try gently baking it in the over and a low temperature to remove the water. However, salt is soooo cheap that it is better to just by another bottle of it at the grocery store.

Answer 2

With respect to the Biblical quote about salt losing its saltiness, you must remember than the salt they had was natural, sea salt, and none too pure, at that. It may have been mixed with other substances, and, if it got wet, the actual sodium chloride would dissolve and flow away in the solution, while the insoluble stuff (dirt, crud, bird droppings, whatever) would remain. Then you'd taste it and say, Hey! Where'd the salt go?

Otherwise, salt has to be decomposed into sodium and chlorine, by electrolysis, just like everybody else said. I hope I answered what you were looking for, though.

Answer 3

Yes, if it is left out in the sun opened or spread out, for long periods of tme.

Answer 4

when you convert it to NaOH and HCL through electrolysis.
