3. A galvanic cell consisting of a Cu2+- Cu half cell versus a H* - H2 half cell was used to determine the pH of an unknown solution. The unknown solution was placed in the hydrogen half cell and the pressure of the hydrogen gas controlled at 1 atm. The concentration of Cu2+ in the Cu2+- Cu half cell was 1.0 M and the emf of the cell at 25°C was determined to be +0.48V. a) Draw the cell and label the anode and the cathode. b) Label which electrode is positive and which is negative. c) Write the balanced equation for the reaction.

Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.
