Question

Three deshelled eggs were put in 3 solutions namely x,y and z respectively. In solution 'x' the egg swelled and in solution 'y' the egg got shrunken and in 'z' the egg remained same . Identity the solution x, y and z ,and explain the phenomena happend in the 3 solutions?

Answer 1

in X diffusion takes place (hypotonic solution)

in y same diffusion takes place(hypertonic solution)
in a it is neutral solution so nothing takes place

Answer 2

X is hypotonic solution ,Y is hypertonic solution and z is isotonic solution.
the phenomenon is deplasomolysis in first case and plasmolysis in second. Or you can say the egg shell got turgid after keeping the egg in solution X and the egg got shrunken when kept in solution Y.

hope it helps,have a nice day
