Nickel forms a series of complexes with aqueous ammonia.
Include also an n-bar curve. Determine the species composition of a solution containing 10 mM total nickel and 30 mM total ammonia. Assume that the solution is buffered at pH 10.3. Then discuss the assumptions you might have made, and how changes in pH might affect this system. Show the same three species I plotted on my graph, and use the same axis range.
