Initially, the container is filled with water (shown with white) and a layer of gas above (green). The reaction generates dissolved gases (red) on the electrodes. As soon as the concentration of dissolved gas reaches a critical value, it is converted into bubbles (green) that rise and merge with the existing layer of gas.
- mushishi 6y agoThank you! I try to understand further: So there is two columns not connected to each other, so doesn't seem it is a circuit. But wait a minute, water conducts... So: The left one is negatively charged, and it gives electrons to H20 which receives them and reacts by being converted to H2 gas and 2hydroxide. The right column is positively charged and the 2hydroxide travels (diffuses?) through water as it is negatively charged, and statistically is more likely to go right because positive column attracts it? (I mean the electrical energy travels as waves but the actual molecules also, just slower?) When 2hydroxide reaches the right end, it breaks into 1) electrons that the column receives happily 2) H20 3) O2 gas. Something like that, perhaps. Interesting but frustrating to not get it fully. No need to answer if don't feel like it!
