Why does the cube lose water?

Doesn't it has the lower concentration of water?

And that makes the salt water a higher concentration of water so why does it not move into the cube instead?

Answer 1

The cube should lose water, because the salt solution surrounding it is more concentrated than the solution WITHIN the potato - so water leaves the potato by osmosis.

More concentrated solute (salts) means less concentrated solvent (water).

If the cubes were placed in distilled water, then water would enter the cubes because the concentration of salts in the cube is higher than the water.
