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 ...

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 ...

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 ...

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 ...

Sodium oxide and potassium oxide dissolve in water to produce alkalis: • Na 2 O(s) + H 2 O (l) → 2 NaOH (aq) • K 2 O(s) + H 2 O (l) → 2 KOH (aq) • 2K(s) + 2H 2 O (l) → 2KOH (aq) + H 2 (g) + heat ...
