 note = {Ultraviolet and visible absorption spectra were taken between 210 and 460 millimicrons in various pH solution (6Ｘ10＾-5 mole/liter) of Potassium bichromate.Cr_2O＾--_7+H_20=2HCrO＾-_4 HCrO＾-_4=H＾++CrO＾--_4 Then,in alkaline solution we can consider the next reaction. Cr20＾--_7+H_2O = 2H＾++2CrO＾--_4 Hydrolysis on Cr_20＾--_7depends upon pH Concentration and Temperature. When the curves calculated from the visible absorption spectra of potassiumbichromate,having a pH greater than 7.35 Coincided, the solution was considered to be lOO% dissociated.\nFrom theoretical calculation,the solution is 1OO% dissociated at pH greater than 6.99. Curves also coincided at pH blow 5.34, but in this case the solution was not　dissociated., 紀要論文},
