Why does salad become soggy and wilted when the dressing has been on it for a while?

Question

The leaves have fresh water in them, but the salt in the dressing causes the water from the leaves to enter the dressing. This is because the water is trying to even out the concentration of salt in the dressing and the leaves, hence lots of water is needed in the dressing to reduce the concentration of salt. This means the water from the leaves goes into the dressing, causing the leaves to appear wilted.
