Consider the following statements:

1. During the process of osmosis, the solvent travels from the concentrated solution to the dilute solution.
2. In the reverse osmosis, external pressure is applied to the dilute solution.

Which of the statements given above is/are correct?
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2

Ans- [D]

Explanation- Statement 1 is wrong as in osmosis solvent molecules moves from low concentration solution to higher concentration solution through a semipermeable membrane.

Statement 2 is also wrong as in reverse osmosis external pressure is applied to the higher concentration solution. SOlvent in this case move from concentrated solution to dilute solution. External pressure applies is above the osmotic pressure.
