Welcome back to the Tommy Technetium channel, get ready for some amazing science experiments. Pure vs. tap water: what’s the difference? Let’s see it clearly with an interesting chemical reaction with butterfly pea flowers. An anthocyanin called delphinidin can be extracted from butterfly pea flowers, which is violet near neutral pH, but changes to blue on addition of metal ions. That’s why delphinidin is a perfect indicator of dissolved minerals that contained in the tap water. Stay tuned for more amazing chemistry experiments and tricks!
