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 ...
(i) They are lustrous, i.e., they have a shiny surface. (ii) All metals are solids except mercury which is liquid at room temperature. (iii) Metals are ductile which means they can be drawn into wires ...

Many of the C–H bonds in hydrocarbons look alike 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 ...
The ability to form multiple carbon–carbon bonds in a controlled sequence and thus rapidly build molecular complexity in an iterative fashion is an important goal in modern chemical synthesis. In ...
Researchers at Rice University, Syzygy Plasmonics Inc. and Princeton University have engineered a key light-activated nanomaterial for the hydrogen economy. In a paper published in the journal Science ...
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 ...
