The spatiotemporal pH and carbon concentration during density-driven convection of CO2 in water

<p>The two supplementary videos showed the spatiotemporal pH and carbon concentration in the Hele-shaw cell by a new experimental technique. They are amied to facilitate the understanding of the density-driven convection of CO2 in water. More details of the research could be found on the manuscript of 'arXiv' named:&nbsp; 'Mapping dissolved carbon in space and time: An experimental technique for the measurement of pH and total carbon concentration in density driven convection of CO2 dissolved in water.'</p>
