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.

0Thank You

Ďãřşháñăã Yadav ? ? ? 6 years, 8 months ago

The hydrostatic pressure which develops on account of osmosis is called osmotic pressure or we can say that the excess pressure that must be applied on the solution to prevent osmosis is called osmotic pressure.

Pressure required to stop osmosis

1Thank You

Yogita Ingle 6 years, 8 months ago

Osmotic Pressure: The flow of solvent from solvent side to solution side (across a semi-permeable membrane) can be stopped by applying some extra pressure. The pressure which is just enough to stop osmosis is called osmotic pressure of the solution.

Fore dilute solutions, osmotic pressure is proportional to the molarity (C) of the solution at a given temperature.

Π=CRT

Here, Π is osmotic pressure and R is the gas constant.

2Thank You

Anjaan Ladka 6 years, 8 months ago

The preesure applied to stop the flow of solvent molecules towards the solution through a semi permeable membrane is known as osmotic preesure.

Peetu Chahal 6 years, 6 months ago

We require different food products for a balance diet. So if we keep on calculating the nutritive value of different food stuff everyday, it requires a lot of time. To solve this problem food groups have been formed. Food providing similar nutrients have been kept in one food group. Required nutrients and variety is automatically achieved in daily diet by selection of foods from each food group.
