Give complete answers to the following (typed preferred, handwritten okay if neat and legible): 1. briefly describe the features you observed in your metallographie specimens. explain what they looked like and/or how you identified them. 2. what is occurring on the atom level that causes grain boundaries. twin boundaries, and phase boundaries to exist (how are each of the types of boundaries formed? hint: they are all formed by different means) 3. for a fixed proportion of each phase in a two phase specimen, how does phase boundary area vary with the size of the second phase particles? 4. for a fixed proportion of each phase in a two phase specimen, how does phase boundary area vary with the shape of the second phase particles? 5. one way of making a metal bowl is to beat a flat sheet of metal into a bowl shape. what microscopic metallographic properties would you want for the metal used to make the bowl? explain why each of these properties is desirable. 6. what was the most important thing you learned from this laboratory exercise?

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
