10. What property of a buffer did you observe in this experiment?
Do Not Answer 11. In each case indicate which reagent, hydrochloric acid or sodium hydroxide, would shift the ionic reaction in the desired direction. + (aq) 2 (g)
12. Assuming that each of the following reversible reactions has reached a state of equilibrium, indicate with an arrow, showing direction of shift, the effect of each change upon the equilibrium. Assume that only one change is made at a time. a) 2 Cl 2 (g) + 2 H 2 O(g) + heat 4 HCl(g) + O (1) Raise P (2)Raise T b) Fe 2 O 3 (s) + 3 H 2 (g) 3 H 2 O(g) + 2 Fe(s) (1) Add Fe(s) (2) Raise P No Change c) 2 NH 3 (g) + heat N 2 (g) + 3 H 2 (1) Raise T (2) Lower P d) CO(g) + H 2 O(g) CO 2 (g) + H 2 (g) (1) Lower T (2) Raise P No Change 2 (g) (g) + heat
