Arrange the following solutions in order of increasing osmotic pressure. Assume `100%` isonisation for electrolytes: `{:(1N NaCl,1N Na_(2)SO_(4),IN Na_(3)PO_(4),,),(I,II,III,,):}`

A

I gt II gt III

B

III gt II gt I

C

II gt III gt I

D

II gt I gt II

Text Solution

Verified by Experts

The correct Answer is:
A
Molarities of `NaCl, NaSO_(4)` and `Na_(3)PO_(4)` are `(M)/(1), (M)/(2), (M)/(3)` respectively.
`:.` Particles furnished by
`NaCl = (M)/(1) xx 2 = 2M`
`Na_(2)SO_(4) = (M)/(2) xx 3 = (3M)/(2)`
`Na_(3)PO_(4) = (M)/(3) xx 4 = (4M)/(3)`

Arrange the following electrolytes in the increasing order of coagulation power for the coagulation of As_(2)S_(3) sol : K_(2)SO_(4) " " CaCl_(2)" " Na_(3)PO_(4) " " AlCl_(3)

Colligative properties i.e., the properties of solution which depends upon the number pf aprticles present in solution are osmotic pressure, depression in freezing point, elevation in boiling point and lowering in vapour pressure. Experimental values of colligative properties for electroetically because electrolytes dissociates to furnish more ions in solution. On the other hand experimentally obtained values of colligative properties for associating nature of solute ate lower than those obtained theoretically. The ratio of experimantal colligative properties to theoretical colligative properties is called as van't Hoff factor (i) . The correct order of osmotic pressure for the solutions : (I) 1N urea , (II) 1N NaCl (III) 1N Na_(2)SO_(4) , (IV) 1N Na_(3)PO_(4) is:

Which one of the following electrolytes is most effective for the coagulation of Fe(OH)_(3) sol and why? NaCl, Na_(2)SO_(4),Na_(3)PO_(4)

Addition of non-volatile solute to a solvent always inceases the colligative properties such as osmotic pressure, DeltaP, DeltaT_(b) and DeltaT_(f) . All these colligative properties are direactly propertional to molality if solutions are dilute. The increase in colligative properties on addition of non-volatile solute is due to incease in number of solute particles. For different aqueous solutions of 0.1 N NaCl, 0.1 N urea, 0.1 N Na_(2)SO_(4) and 0.1 N Na_(3)PO_(4) solution at 27^(@)C , the correct statement are : (P) The order of osmotic pressure is, NaCl gt Na_(2)SO_(4) gt Na_(3)PO_(4) gt urea (Q) pi = (DeltaT_(b))/(K_(b)) xx ST for urea solution (R) Addition of salt on ice increases its melting point (S) Addition of salt on ice brings in melting earlier
