The chemistry of the Sunflower dye found in McCormick’s Color from Nature food dyes is explored in this post. This is the last in a three-part series in which several experiments and demonstrations that can be done with Color from Nature food dyes are described.
The chemistry of the Berry dye found in McCormick's Color From Nature food colors is explored. This is part two of a three-part series in which the chemistry of McCormick's Color From Nature food colors is presented.
Celebrating National Chemistry Week 2015: Chemistry Colors Our World
The October 2015 issue of the Journal of Chemical Education is now available online to subscribers. National Chemistry Week, a community-based annual event uniting ACS local sections, businesses, schools, and individuals in communicating the value of chemistry in our everyday life, is being celebrated October 18–24, 2015 with the theme “Chemistry Colors Our World”. Articles in this issue can help you make the most of this annual celebration.
An electric current is passed through a sulfuric acid solution. Gases collected at the electrodes are tested.
This animation simulates the electrolysis of a neutral aqueous solution.
In aqueous hydrochloric acid, the electrolyzed solution is acidic at both electrodes.
In aqueous sodium hydroxide, the electrolyzed solution is basic at both electrodes.
In neutral sodium chloride, base is produced at the cathode and acid at the anode.
An electric current is passed through a sodium sulfate solution. Gases are collected at the electrodes are tested for pH.
