When a hydrophobic substance like a hydrocarbon is dissolved in water, a clathrate cage of ordered water molecules is formed about it. If we consider only the effects on water, what do you expect the sign of ∆S to be for this process? Explain your answer.
The distribution of Na* ions across a typical biological membrane is 10 mmol/dm3
inside the cell, and 140 mmol/dm³ outside the cell. At equilibrium, the
concentrations across the membrane are equal. What is the Gibbs energy
difference across the membrane at 37°C?
The stated difference in concentration MUST be maintained by coupling to
reactions that have at least your calculated difference of Gibbs energy.
Ans: 6.8 kJ/mol
Solution A contains 100 mmol/L glucose and Solution B contains 50 mmol/L NaCl. Assume that gNaCl is 2.0, σglucose is 0.5, and σNaCl is 0.8. If a semipermeable membrane separates the two solutions, what is the direction of water flow across the membrane?

- Aspirin is a weak acid with a pKa of 3.5 (the ionizable H is shown in red):It is absorbed into the blood through the cells lining the stomach and the small intestine. Absorption requires passage through the plasma membrane, the rate of which is determined by the polarity of the molecule: charged and highly polar molecules pass slowly, whereas neutral hydrophobic ones pass rapidly. The pH of the stomach contents is about 1.5, and the pH of the contents of the small intestine is about 6. Is more aspirin absorbed into the bloodstream from the stomach or from the small intestine?

The pieces of potato were initially the same weight, shape, and size. Each potato piece was submerged into a beaker containing one of the sucrose concentrations for 30 minutes. The final weight of the potato was measured and recorded in the table. Which TWO conclusions can be correctly drawn from this data? A In the 0.4 mol/dm3 solution, the sucrose molecules moved across the semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration (the sucrose solution), leading to a decrease in the weight of the potato. B In the 1 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato.

The researcher then uses an experimental apparatus ,where he notes that, at room temperature (300K) and atmospheric pressure (101.325 kPa), distilled water flows naturally into the solution compartment. However, when he applies an extra pressure of 1000 Pa he observes that the flow of distilled water ceases and the system is in balance. Calculate the molar mass of this protein, in kDa (1 Da = 1 g/ mol); Why does the flow of distilled water cease with the application of the pressure of 1000 Pa?
