Question

How does osmosis relate to solute concentration?

Answer 1

Hint: Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration and solute concentration is the amount of solute and particles that are present in solution.

Complete step by step answer:
Osmosis is a process that occurs between two containers separated by a semi-permeable barrier. If the barrier has pores large enough to allow water molecules to pass but small enough to block the molecules of a solute, the valve will flow from side with smaller concentration of solute to the side with larger concentration.
This process is continued until concentration on both sides will not be some.
Example: Osmosis occurs when sugar solution and water are separated by semi permeable membranes. The solution’s large sugar molecule cannot pass through the membrane into, so the small water molecule moves through the membrane until equilibrium is achieved.
Osmosis occur in human body as main or important process of transport
Osmosis is free of energy cost.

Note: To stop osmosis to occur there must be resistive pressure called as osmotic pressure. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
$\pi =\text{i c R T}$
$\pi =$ osmotic pressure
$\text{i}=$ van’t hoff index
$\text{c}=$ Molar concentration of solute
$\text{T}=$ Temperature
$\text{R}=$i deal pras constant.
