The chemistry of acids and bases in food Many foods naturally contain acids, such as citric acid in citrus fruits, acetic acid in vinegar, and lactic acid in fermented dairy, which contribute sourness ...

Chemists have long known that catalytic Lewis acidic and Lewis basic sites on metal and metal oxide surfaces help spark a range of reactions that are important in industrial chemical and fuel ...

Introduction Did you know that the juices in your stomach are nearly as acidic as lemon juice? Fortunately, your stomach has special cells that act as a barrier to the acid, preventing it from ...

Acids are part of lots of chemical reactions. All chemicals have different properties, one of them is whether it is acidic or basic. Acids are part of lots of important chemical reactions, everything ...

Use a cabbage detector to learn how acids (like vinegar) and bases (like soap) change the color of water. Lose the Blues with CO 2 Carbon dioxide is one of life’s most essential gases. Test how much ...

Researchers are tapping into Lewis acid–base chemistry to make solid-state, aqueous, and even polymer-based energy storage safer, longer-lasting, and more powerful. By coordinating specific ions or ...

Terpenoid cyclases catalyze the most complex reactions in biology, in that more than half of the substrate carbon atoms often undergo changes in bonding during the course of a multistep cyclization ...
