8. Calculate pH of the following buffer solutions (HHE).
a. [H2CO3] = 0.6 M & [NaHCO3] = 0.3 M
b. [TRIS cation]= 0.2 M & [TRIS] = 0.05 M
9. For the two buffers in question 8, calculate the pH of the buffer after the buffer is diluted 10 fold (i.e., concentrations are decreased by a factor of 10)
(8a) _______________ (8b) _______________
10. What must be the ratio of be to prepare a buffer at pH = 7.40? (use the HHE)
