1 5 points A galvanic cell consists of an Cu(s)|Cu2 (aq) half-cell and a Cd(s) |Cd2+ (aq) half-cell connected by a salt bridge. Oxidation occurs in the cadmium half-cell. The cell can be represented in standard notation as Cu²+ (aq)|Cu(s)||Cd(s) Cd²+ (aq) Cd² (aq)|Cd(s)||Cu(s)|Cu² (aq) Cd(s) Cd²+ (aq)||Cu(s) Cu²(aq) Culs) Cu2(aq)|Cd(s)/Cd2 (aq) Cd(s) Cd²*(aq)||Cu²+ (aq)|Cu(s) 2 5 points A 28.9 mL sample of 0.176 M formic acid (HCHO₂) is titrated with 0.176 M NaOH. Calculate the pH after the addition of 28.9 mL of NaOH. (For HCHO₂: K₂=1.76 * 10-4) Hint: Determine the equivalence point so you know where you are in the titration. Report your answer with 2 places past the decimal point. Type your answer... 5 points A galvanic cell is composed of these two half-cells, with the standard reduction potentials shown: Co2 (aq) + 2e-Co(s) -0.28 volt Cd2+ (aq) + 2e-Cd(s) -0.41 volt The actual concentrations are: (Co²(aq)] -0.0013 M. (Cd2+)-0.137 M. What is the potential in volt of this galvanic cell? (T-298K)
