acid. Salt is sodium cloride NaCL. google it. It has a residual value (stays in the soil) so don't plan on going anything else unless you remove dirt and refill with top soil.
Rock salt works best to kill plants.

Why does salt kill plants? Salt takes out the water in plants. Plants need a lot of water to survive. Just like people Without water, the plants dry up and die.

yes it starves the plant for water by messing with the osmatic pressure of the water outside of the plants root cells. It does the same for fish and all other living things.If the concentration of sodium ions is higher outside the cell and the H2o concentration is higher inside these will try to equalize. this means excess sodium in the cell and water flowing out. The salt adapted plants can hold an even higher level of salt in them than what is around them but only in some parts and actively transport and dispose of it. They can still only stand salt up to a certain level. The chlorine is incidental.

Salt draws the water out of a plant's cells, essentially killing it by dehydration.

It dehydrates it until all the essential fluids seeps out of the poor plant.
