 Abstract
The purpose of this research was to analyze and improve the experiment, observing the color change under compression on the equilibrium of system, described in high school and general chemistry textbooks. Chemistry textbooks described that the reddish brown color got lighter on the compression of system. This misinterpretation was due to no consideration of concentration increase by the volume decrease. In order to propose a correct interpretation, the changes of color and temperature on compression were quantitatively measured and compared with theoretical studies. In addition, an improved experiment, excluding the effect of concentration increase, was proposed to observe only the color change of the net equilibrium shift.
