Chemistry Question on Solutions
Highest osmotic pressure is shown by a solution of
A
0.1 M aluminium sulphate
B
0.1 M potassium nitrate
C
0.1 M magnesium chloride
D
0.1 M barium chloride
Answer
0.1 M aluminium sulphate
Explanation
Solution
Osmotic pressure (π)=iCRT . The value of i is highest for Al2(SO4)3, hence it will show highest osmotic pressure.
