To watch a shortened version of the video records, pull the mouse on the first pictures of them displayed below.
     In the case of the NaOH+CuCl₂ reactions the concentration of outer electrolyte was of 8 M/l, that of the inner electrolyte of 0.732 M/l. In the case of the NaOH+AgNO₃ reaction the concentration of outer electrolyte was of 8 M/l, that of the inner electrolyte of 0.41 M/l.
     The pattern formation was taking place between a microscope slide and a cover glass. The pictures were taken by a video microscope.
