The highest osmotic pressure corresponds to the following solution

Question

The highest osmotic pressure corresponds to the following solution (A)  M/10 urea (B)  M/10 glucose (C)  M/10 HCl  (D)  M/10 BaCl2

Tardigrade Admin · Accepted Answer

Osmotic pressure, π = icRT For urea and glucose, i = 1 For HCl and BaCl2, i > 1 Due to high ionisation of BaCl2 than HCl, iBaCl2 > iHCl ∴ Order of osmotic pressure will be BaCl > HCl > Urea = glucose

Q. The highest osmotic pressure corresponds to the following solution

$M /10$ urea

$M /10$ glucose

$M /10 H Cl$

$M /10 B a C l_{2}$

Osmotic pressure, $π = i c RT$
For urea and glucose, $i = 1$
For $H Cl$ and $B a C l_{2}, i > 1$
Due to high ionisation of $B a C l_{2}$ than $H Cl$ ,
$i_{B a C l_{2}} > i_{H Cl}$
$∴$ Order of osmotic pressure will be
$B a Cl > H Cl >$ Urea $=$ glucose

Q. The highest osmotic pressure corresponds to the following solution

M/10 urea

M/10 glucose

M/10HCl

M/10BaCl2​

Osmotic pressure, π=icRT For urea and glucose, i=1 For HCl and BaCl2​,i>1 Due to high ionisation of BaCl2​ than HCl, iBaCl2​​>iHCl​ ∴ Order of osmotic pressure will be BaCl>HCl> Urea = glucose

$M /10$ urea

$M /10$ glucose

$M /10 H Cl$

$M /10 B a C l_{2}$

Osmotic pressure, $π = i c RT$
For urea and glucose, $i = 1$
For $H Cl$ and $B a C l_{2}, i > 1$
Due to high ionisation of $B a C l_{2}$ than $H Cl$ ,
$i_{B a C l_{2}} > i_{H Cl}$
$∴$ Order of osmotic pressure will be
$B a Cl > H Cl >$ Urea $=$ glucose
