According to the picture:
1. Calculate the average charge on arginine when pH=9.20 . (Hint : Find the average charge for each ionizable group and sum these together.)
Express your answer using two significant figures. (please show work)
2. You can neglect contributions from form I . Why?
| A. Species I can be neglected because they are not responsible for the ionization of water. | B. Species I can be neglected because they are not involved in the calculations of the pI value. | C. Species I can be neglected because they are not charged. |
| D. Species I can be neglected because they are present at an insignificant concentration. |
