Calculate the ph of a 0.208 0.208 m solution of ethylenediamine ( h 2 nch 2 ch 2 nh 2 h2nch2ch2nh2). the p k a pka values for the acidic form of ethylenediamine ( h + 3 nch 2 ch 2 nh + 3 h3+nch2ch2nh3+) are 6.848 6.848 ( p k a1 pka1) and 9.928 9.928 ( p k a2 pka2). ph = ph= calculate the concentration of each form of ethylenediamine in this solution at equilibrium.
[ h 2 nch 2 ch 2 nh 2 ] =
[h2nch2ch2nh2]= m m
[ h 2 nch 2 ch 2 nh + 3 ] =
[h2nch2ch2nh3+]= m m
[ h + 3 nch 2 ch 2 nh + 3 ] =
[h3+nch2ch2nh3+]=

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
