Current Question (ID: 18117)

Question:

$\text{Isotonic solutions have the same:}$ $1. \text{Vapour pressure}$ $2. \text{Freezing temperature}$ $3. \text{Osmotic pressure}$ $4. \text{Boiling temperature}$

Options:

1. $\text{Vapour pressure}$
2. $\text{Freezing temperature}$
3. $\text{Osmotic pressure}$
4. $\text{Boiling temperature}$

Solution:

$\text{Hint: } \pi_1 = \pi_2$ $\text{Isotonic solutions have same osmotic pressure}$ $\pi_1 = C_1 \text{ST}$ $\pi_2 = C_2 \text{ST}$ $\text{so at same temp, if } C_1 = C_2$ $\pi_1 = \pi_2$ $\text{Two solutions having the same osmotic pressure across a semipermeable membrane is referred to as an isotonic solution}$
