QUESTION: Why does the water come out from the cucumber when we add salt in it?

ANSWER The water come out from the cucumber when we add salt because of hyper tonic and hypo tonic conditions. The outside environment is hyper tonic to the inside environment of the cucumber. Since there is less water outside or none and a high concentration of salt and there is a high concentration of water inside the cucumber and low salt or none at all. Through diffusion water will go from high to low concentration hence into to out. When water moves out its called osmosis.
