Explanation
Normality = Basicity × Molarity = 3N
98 g H2SO4 = 1 mol
P ∝ T. If T is doubled, P is also doubled.
Conc. of particles of 0.01 M urea, NaCl and Na2SO4 = 0.01 M, 0.02 M, 0.03 M resp. i.e. they are in the ratio 1 : 2 : 3. Hence depression in freezing point will be in the same ratio.
3.42 g of sucrose/lit = 0.1 M, 0.18 g glucose in 0.1 L = 0.1M.
By definition
Copper ferrocyanide ppt acts as a semipermeable membrane.
The best method for determination of osmotic pressure is Berkeley and Hartley method.
Colligative properties depend on the number of solute particles present in the solution and their concentration.
Hence,
Osmotic pressure = (effective molarity of solution)(ideal gas constant)(absolute temperature).
Here, effective molarity = Van’t Hoff factor × molarity
∴0.5 M C2H5OH(aq) i =1 effective molarity = 0.5M
0.1M Mg3(PO4)2(aq) i = 5 × effective molarity = 0.5M
0.25M KBr(aq) i = 2× effective molarity = 0.5M
0.125M Na3PO4(aq) i = 4× effective molarity = 0.5M
Hence all colligative properties are same. Therefore they all have same osmotic pressure.
