You have created some artificial membrane vesicles that have a higher ph inside

Question

You have created some artificial membrane vesicles that have a higher ph inside the aqueous solution outside. To sample 1 of these vesicles you add HCL and to the other sample you add some DNP with equivalent acidity and then measure the internal ph of vesicles.

Explanation / Answer

The internal pH of vessel 1 remains unchanged, while the internal pH of vessel 2 decreases. This is because DNA (2,4-dinitrophenol) is hydrophobic in nature and it can readily cross cell membrane. It can carry hydrogen ions across the cell membrane from the heigher concentration (outside) to lower concentration (inside) thus, reducing the internal pH.

HCl cannot carry protons across the cell membrane thus, the pH remains unchanged in vessel 1.
