green colored namesIts acid–base properties are most important. In aqueous solution, glycine is amphoteric: below pH = 2.4, it converts to the ammonium cation called glycinium. Above about 9.6, it converts to glycinate. Glycine functions as a bidentate ligand for many metal ions, forming amino acid complexes. A typical complex is Cu(glycinate)2, i.e. Cu(H2NCH2CO2)2, which … flowsleepingWebApr 29, 2024 · The question is to find out the pH of 0.01 M glycine solution. It is given that K a 1 = 4.5 ⋅ 10 − 3 and K a 2 = 1.7 ⋅ 10 − 7. Glycine is N H X 2 C H X 2 C O O H. The two K a values correspond to the ionization of C O O H and N H X 2. My idea was to average the two K a values and take log to get pH. However this is not yielding the correct answer. flow slamWebJul 7, 2024 · Reports show the solubility of glycine in water to be 4.25 and 2.733 g/100 mL.
