What is the thumb rule to consider for osmotic pressure? |
| A. | 1 psi for every 86 ppm of na |
| B. | 2 psi for every 86ppm of na |
| C. | 1 psi for every 43 ppm of na |
| D. | 2 psi for every 43 ppm of na |
| Answer» A. 1 psi for every 86 ppm of na | |
| Explanation: the tendency of a pure solution constituting low solute concentration to flow into solution constituting higher solute concentration is known as osmosis. when pressure greater than osmotic pressure is applied then reverse osmosis takes place. the thumb rule for the consideration of osmotic pressure is 1 psi for every 86 ppm of na. | |
