Question

Realation between value of osmotic pressure of 0.1M solutions of KNO3(p1) and CH3COOH(p2) is 1) pi greater than p2 2) p1 = p2

Answer 1

P1 =  i x n/v x Rx T , where n/v = 0.1 ,  i = 1 ( its a strong electrolyte hence dissociate 100%) 
 P2 =  i x n/v x R X T  ,  i < 1 as its a weak electrolyte, n/v = 1 
 therefore P1 > P2

Answer 2

Answer:

1) p1 > p2

Explanation:

Osmotic pressure is the pressure which is applied to a solution to prevent its inward flow .

Now,

Osmotic Pressure = iCRT

We know KNO3 is a strong electrolyte that is is completely dissociates into ions and conduct electricity compared to CH3COOH which is in turn a weak electrolyte.

Now according to the formula

Osmotic Pressure = iCRT

i=1 for strong electrolyte

and i<1 for weak electrolyte

so

and 1) p1>p2 is correct.
