Put simply, aluminum production starts with the metal-rich ore bauxite. After a series of chemical reactions, a powdery ...

The work could be a step toward understanding the effects behind the phenomenon of static electricity, in which electric charge accumulates on materials after they are rubbed or touched together.

This is due to the increased positive charge on the metal ion and the increased number of electrons that are delocalised, resulting in stronger bonding.

When rock salt is used on our sidewalks and roads, there is science happening at the molecular level. Dr. Xavier Prat-Resina ...

An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The positive and negative ions attract each other and form the ionic compound ...

The acid reacts with any carbonate ions present. This removes them, so stopping them giving a false positive result. Sulfuric acid, H 2 SO 4 (aq), contains sulfate ions. These would react with ...
