What is Van't Hoff equation for osmotic pressure ?

Text Solution

Verified by Experts

(i) Boyle-Van.t Hoff law :
" Temperature remaining constant , the osmotic pressure` pi` of a dilute solution is directly proportional to the concentration of the solution ."
`rArr pi prop C or,pi prop 1/V rArr piV = K.`
