Question

Explain your observations in the following with reason involved in this process.

(a) Salt is applied to raw mango pieces

(b) Dried raisins are kept in water for a few hours

Answer 1

a) When salt is applied to raw mango pieces, then it will loose water. This happens due exosmosis from the cells in the presence of salt. Water moves out of the cells of mango due to osmosis and hence water is seen on the raw mango pieces.

b) When dried raisins are kept in water, then they swell up by absorbing water. This happens due to endosmosis from the cells. Water moves inside the raisins due to osmosis as concentration of solutes is higher inside the raisins.
