摘要：

The pH-imaging sensor is applied to visualization of ionic diffusion in an electrochemical system. Redistribution of the pH value due to diffusion of ions after electrolysis is measured to determine the diffusion coefficients of anions and cations. Dependence of the diffusion coefficient on the molecular weight of ions is investigated. Applicability of the pH-imaging sensor to quantitative analysis of dynamics in a chemical system is demonstrated.
