At the same temperature, each of the following solution has the same osmotic pressure except — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Osmotic pressure depends on $i \times C$. Sucrose ($1 \times 0.140 = 0.140$), KCl ($2 \times 0.07 = 0.140$), $\text{Ca(NO}_3\text{)}_2$ ($3 \times 0.070 = 0.210$), Urea ($1 \times 0.140 = 0.140$). $\text{Ca(NO}_3\text{)}_2$ has a different value. Therefore, correct answer is C.
