Adding carbon dioxide to the Instant Ocean + bromothymol blue
Neutralizing the acidified ‘ocean’ with baking soda solution.

Just read Elena Aguilera’s post on the end of the year and keeping it going with projects and labs and fun. This was much more fun than I expected for a seriously serious topic: 5. Ocean Acidification and Neutralization and links CO2 in breath to acidification of both fresh and salt water using bromothymol blue indicator, then making it alright again with baking soda solution. They can compare the number of drops needed to neutralize the different water types. Very interesting to consider which type of water is most vulnerable to changing pH. Plus a nice way to link back again to the problems with oil and fold in expertize of some students who specialized in that for their multi media projects.

I think there was a buzz of doing ‘real’ chemistry finally, and the colors are genuinely beautiful in the sharp morning light.
