Question

write what will happen and why in the following situations:
(a) eggs without shells and first placed in pure water and then in a salt solution
(b) spinach leaves are boiled first and then put in sugar solution​

Answer 1

When an egg without shell is placed in concentrated salt solution for 5 minutes - The egg shrinks due to loss of water by the process of osmosis. ... - The egg gain water and swells. Reason. The concentration of water is much more on the outside thus water moves into the egg cells through egg cell membrane by osmosis.

The solute content within the leaves will falls out during heating due to osmosis. The cells are being destroyed by heating and boiling up further. Cells are set to die.

please mark me brain mark list

Answer:

A) The egg shrinks due to loss of water by the process of osmosis. ... The concentration of water is much more on the outside thus water moves into the egg cells through egg cell membrane by osmosis.

B) When spinach leaves are boiled, this will shrink due to high temperature. The solute content within the leaves will falls out during heating due to osmosis.
