The osmotic pressure of 5 % (mass-volume) solution of cane sugar at 150 °C (mol. mass of sugar = 342 g/mole) is:
| 1. | 4 atm | 2. | 5.07 atm |
| 3. | 3.55 atm | 4. | 2.45 atm |
Aqueous solutions of 0.004 M Na2SO4 and 0.01 M Glucose are isotonic. The degree of dissociation of Na2SO4 is-
1. 25%
2. 60%
3. 75%
4. 85%
The relationship between osmotic pressure at 273 K, when 10 gm glucose (P1), 10 gm urea (P2), and 10 gm sucrose (P3) are dissolved in 250 ml of water, is-
1. P1 > P2 > P3
2. P3 > P1 > P2
3. P2 > P1 > P3
4. P2 > P3 > P1
An aqueous solution containing 1 g of urea boils at 100.25 °C. The aqueous solution containing 3 g of glucose in the same volume will boil at:
1. 100.75 °C
2. 100.5 °C
3. 100 °C
4. 100.25 °C
At a given temperature, osmotic pressure of a concentrated solution of a substance:
| 1. | is higher than that of a dilute solution. |
| 2. | is lower than that of a dilute solution. |
| 3. | is same as that of a dilute solution. |
| 4. | cannot be compared with osmotic pressure of dilute solution. |
Preservation of fruits against bacterial action by adding sugar is an example of-
1. Exosmosis
2. Reverse-osmosis
3. Diffusion
4. Capillary action
If 'A' contains 2 % NaCl and is separated by a semi permeable membrane from 'B', which contains 10 % NaCl, then the event that will occur is
1. NaCl will flow from 'A' to 'B'
2. NaCl will flow from 'B' to 'A'
3. Water will flow from 'A' to 'B'
4. Water will flow from 'B' to 'A'
