The chemistry of hydrangea color change can be understood in the context of acid/base chemistry. Specifically inorganic chemistry explains the shift from red/pink to blue blooming flowers under acidic soil conditions. Do you know what is key to changing the color of these flowers?
Prof. Henry Schreiber and his group studied and reported on hydrangea color change chemistry. To find out the key to hydrangea color change chemistry read the article in American Scientist which summarizes Schreiber’s findings: Curious Chemistry Guides Hydrangea Colors
