is a mixture of two strong acids -- hydrochloric and nitric acids- - that can dissolve gold, a noble metal. This reaction can be put to use. Watch as Reactions employs some acid know-how to ...

A solution with a pH value which is less than 7 is acidic. The acids which react with metals usually have quite a low pH, of either 3 or less. Some metals react with acids and when they do the ...

Life in extreme environments -- hot acids and heavy metals, for example -- can apparently make very similar organisms deal with stress in very different ways, according to new research. Life in ...

Here, we report a new and efficient metal-free carbon–carbon bond-forming coupling between tosylhydrazones and boronic acids. This reaction is very general and functional-group tolerant.
