Question

Assuming each salt to be 90% dissociated which of the followings will have highest osmotic pressure?

• A. Decimolar $A{l}_2(S{O}_4{)}_3$
• B. Decimolar $BaC{l}_2$
• C. Decimolar $N{a}_{2}S{O}_4$
• D. A solution obtained by mixing equal volumes of (b) and (c) and filtering

Answer 1

The correct option is A Decimolar $A{l}_2(S{O}_4{)}_3$

Option (A) is correct. Decimolar $A{l}_2(S{O}_4{)}_3$ will have highest osmotic pressure as it furnishes maximum number (5) of ions.
