The chemical trafficlight

From NileRed.

In this video, I’ll be recreating the popular demonstration called the Chemical Traffic Light Reaction.

Note: I made a mistake in the video. I said the carbonate solution would have a pH around 8-9, but it would actually be closer to 11-12. I was thinking of sodium bicarbonate when I said that.
