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 ...

The latest short science news items from C&EN. The researchers trigger the reaction with violet light. First, there is an electron transfer from an oxidant, a N-alkoxyphthalimide ester, to the ...

A range of production processes frequently employ acid mixtures comprised of two or three acids; for example, nitric acids, sulfuric acids and hydrochloric acids. In order to use these acids safely ...

The humble stir bar is a ubiquitous workhorse of the chemistry lab that has swirled its way into researchers’ hearts. But it seems that magnetic stirrers have also been mixing things up in a different ...
