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 ...

Metals react differently. Some are very reactive and others are unreactive. Observations of reactions can be used to put metals into an order of reactivity. For example, copper is unreactive so it can ...

Many of the C–H bonds in hydrocarbons look similar to chemical reagents. As a result, synthetic chemists often have to install activating or directing groups to get reactions to occur at C–H bonds of ...

Hydrogen carbonate, also called bicarbonate, is an acid salt formed from carbonic acid and contains hydrogen carbonate ions. Most hydrogen carbonates are thermally unstable and decompose into ...

A new one‑step, water‑, acid‑, and alkali‑free method for extracting high‑purity lithium from spodumene ore has the potential to transform critical metal processing and enhance renewable energy supply ...

Aliphatic amines are popular motifs in biologically relevant molecules, so chemists have myriad tools for assembling C–N bonds. Methods that make those bonds enantioselectively are particularly ...
