The relationship between the values of osmotic pressures of`0.1M`solutionsof`KNO_(3)(P_(1))`and`CH_(3)COOH(P_(2))`is

Options

A. `P_(1)gtP_(2)`
B. `P_(2)gtP_(1)`
C. `P_(1)=P_(2)`
D. `P_(1)//(P_(1)+P_(2))=P_(2)//((P_(1)+P_(2))`

Answer

A

Explanation

For equimolar solution,osmotic pressure depends on the value of van't Hoff factor(i)
`:.` Osmotic pressure`prop i` For `KNO_(3)`(being strong electrolyte),completing ionizes,`i_(1)=2`
But for `CH_(3)COOH,i_(2)=1+prop`
`:.i_(1) gt i_(2)` but `P_(1) lt i_(1)`
`P_(2) lt i_(2)`
`:.P_(1) gt P_(2)`
