Decomposition of Salt in Water Salt (NaCl) decomposes inwater into sodium (Na+) and chloride (Cl-) ions accordingto the law of uninhibited decay. If the initial amount of saltis 25 kilograms and, after 10 hours, 15 kilograms of salt is left,how much salt is left after 1 day? How long does it take until1/2 kilogram of salt is left?
