Question

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

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

Answer 1

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

$A{l}_2(S{O}_4{)}_3$ furnishes maximum number of ions.
