Test tube 1 - potato went from 10g to 7g.
Test tube 2 - potato went from 10g to 12g.
Which test tube has a hypertonic solution and which one is hypotonic and why..???!!

The potato that got lighter was in a hypertonic environment and the potato that got heavier was in a hypotonic environment. When there is a differing of concentration of salts between the inside and outside of the potato, the tendency of water is to move where there is less of it until equilibrium is achieved.
