Question

Removing a nonpolar surface from water is expected to do the following to the entropy of the system: (decrease/increase/cause no change) A researcher needs to prepare a buffer for studying a molecular interaction at a constant pH of 7.4. This interaction is known to release protons that could cause pH changes in the buffer. To maximize the buffeting capacity of the buffer, one could choose a buffer system that has a pKa that is (below/above/equal to) the target pH. The main buffer in human blood plasma consists of this acid/conjugate base pair (chemical formula) Excluding hydrogen bonding and hydrophobic interaction, the shortest range non-covalent Interaction is (no option provided)

Explanation / Answer

1) entropy of the system increase

2) equal to the target pH

3) The buffer of human blood plasma contains carbonic acid and bicarbonate ion i.e H2CO3/HCO3-

4) The shortest range of non-covalent interaction is dipole-dipole interaction.
