Q: What is the correct answer for this exam Chemistry Q55?

The correct answer is D. Sol. On side (I) $C_1 = \frac{18/180}{0.1} = 1M$. On side (II) $C_2 = \frac{30/180}{250/1000} = \frac{2}{3}M \approx 0.67M$. Since $C_1 > C_2$, water will flow from chamber-II to Chamber-I. So Statement I is false.For Statement II: $\pi = iCRT$. For K₂SO₄, $i = 3$. $\pi = (3 \times \frac{50 \times 10^{-3}}{174}) \times 0.083 \times 300 = 0.0107$ bar. So Statement II is true.

The correct answer is D. Sol. On side (I) $C_1 = \frac{18/180}{0.1} = 1M$. On side (II) $C_2 = \frac{30/180}{250/1000} = \frac{2}{3}M \approx 0.67M$. Since $C_1 > C_2$, water will flow from chamber-II to Chamber-I. So Statement I is false.For Statement II: $\pi = iCRT$. For K₂SO₄, $i = 3$. $\pi = (3 \times \frac{50 \times 10^{-3}}{174}) \times 0.083 \times 300 = 0.0107$ bar. So Statement II is true.

Q: What are the options for this this exam Chemistry question?

A. Both Statement I and Statement II are true · B. Both Statement I and Statement II are false · C. Statement I is true but Statement II is false · D. Statement I is false but Statement II is true

Question

Q.55. Given below are two statements :[Figure: A semi-permeable membrane separates Chamber 1 containing 18 g glucose in 100 mL aqueous solution from Chamber 2 containing 30 g glucose in 250 mL aqueous solution.]Statement I: H₂O molecules move from the chamber 1 to chamber 2.Statement II: The osmotic pressure of a solution prepared by dissolving 50 mg of potassium sulphate (molar mass = 174 g/mol) in 2 L of water (at 27°C) is 0.0107 bar. (Given : R = 0.083 dm³ bar K⁻¹ mol⁻¹ and assume complete dissociation of electrolyte)In the light of the above statements, choose the correct answer from the options given below :

FirstInTest · Accepted Answer

Sol. On side (I) $C_1 = \frac{18/180}{0.1} = 1M$. On side (II) $C_2 = \frac{30/180}{250/1000} = \frac{2}{3}M \approx 0.67M$. Since $C_1 > C_2$, water will flow from chamber-II to Chamber-I. So Statement I is false.For Statement II: $\pi = iCRT$. For K₂SO₄, $i = 3$. $\pi = (3 	imes \frac{50 	imes 10^{-3}}{174}) 	imes 0.083 	imes 300 = 0.0107$ bar. So Statement II is true.
