How are the acidities of tap and sparkling water related to the acidity of the ocean? Don't the people who processed the drinking water exercise basic (no pun intended) control over its pH?
- panzagl 10y agoHe meant that the concept is easy to explain and demonstrate.
- sqeaky 10y agoPresumably showing them that these little pieces of paper are cheap and effective tests make it easier to believe that people elsewhere are performing tests reliably. If I showed someone how to use these paper tests and showed how reliable they were, then showed a video of someone testing ocean water they, just might, just barely, hopefully might be more likely to believe me.
- simonsarris 10y agoYou can look at tap water and sparkling (tap water + CO2 injection) and note that the sparkling water is more acidic. (Because CO2 dissolves in water into carbonic acid) CO2 + H2O ⇌ H2CO3 CO2 injection to make sparkling water is a lot like CO2 being absorbed by the oceans.
- djrogers 10y ago> CO2 injection to make sparkling water is a lot like CO2 being absorbed by the oceans. So the purpose of the demonstration is to show that we're making the oceans yummier? Awesome!
- schoen 10y agoOh, I completely missed the point of the demonstration! I though there was going to be some way in which one of the kinds of water had changed from its historical pH due to indirect effects of human activity (which didn't make sense to me).
- criddell 10y agoI think they mean to take tap water and carbonate it. I do this at home with a soda stream machine.
