Consider separate solutions of 0.500 M C2H5OH(aq), 0.100 M Mg3(PO4)2(aq), 0.250 M KBr(aq) and 0.125 M Na3PO4(aq) at 25ºC. The correct statement about these solutions, assuming all salts to be strong electrolytes is:
1. | 0.100 M Mg3(PO4)2(aq) has the highest osmotic pressure |
2. | 0.125 M Na3PO4(aq) has the highest osmotic pressure |
3. | 0.500 M C2H5OH(aq) has the highest osmotic pressure |
4. | They all have the same osmotic pressure |
Given that the pH of a 0.1 M monobasic acid is 2, what is the osmotic pressure at a given temperature T?
1. 0.1RT
2. 0.11RT
3. 1.1RT
4. 0.01RT
During osmosis, the flow of water through a semi-permeable membrane is :
1. From solution having higher concentration only
2. From both sides of the semi-permeable membrane with equal flow rates
3. From both sides of the semi-permeable membrane with unequal flow rates
4. From solution having lower concentration only
