WebbpH imaging. This is a measurement method in which pH is determined at multiple points and the results displayed as an image. It has been attracting attention as a technology for visualizing pH distributions. Historically, the method mentioned in Section (1), which combines pH indicators and microscopes, has been used to measure the pH inside cells. In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H ions) are measured to have lower pH values than basic or alkaline solutions.
