Consider the following galvanic cell: Pt(s)|Br- (aq)|Br2(1)||Cr2O72- (aq), Cr3+ (aq)|Pt(s) C. Calculate the equilibrium constant for this reaction at 25 °C using electrochemical data. d. Calculate the cell potential for this galvanic cell assuming the following conditions: pH = 0 · [Cr2O72-] = 1.0 M Br-) = 0.20 M, (Cr3+] = 1.0 x 10-5 M T = 25 °C. Create and upload...

Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...

1. A buffer called "Tris" is widely used in biochemistry. The (neutral) compound "Tris" itself is a weak base, so we'll notate it as "B." The pk, of its conjugate acid (HB) is 8.07. The overall goal of this problem is to calculate the pH change of a Tris buffer upon addition of some strong base. (a) Assume that you have a pH 8.40 Tris buffer...

4. Buffer capacity refers to the amount of acid or base a buffer can absorb without a significant pH change. It is governed by the concentrations of the conjugate acid and base components of the buffer.
