sodium bicarbonate. When this base interacts with an acid, it releases carbon dioxide, the chemical responsible for fluffing up baked goods. This reaction is why you can test the freshness of ...

A carbon capture device that generates electricity as it selectively absorbs carbon dioxide has been demonstrated ... creation of a voltage across it. To test this concept, the team devised ...

Enter reactive carbon capture, where carbon dioxide dissolved in alkaline solutions, like bicarbonate solutions, can be ...

The mixture should start to foam as the sodium bicarbonate reacts with the ethanoic acid and produces bubbles of carbon dioxide gas. Image caption, STEP 4: Pour the carbon dioxide onto the flame.
