Dilute H2SO4 attacks iron, aluminium, zinc, manganese, magnesium and nickel, but reactions with tin and copper require the acid to be hot and concentrated. Lead and tungsten, however, are resistant to sulfuric acid. The reaction with iron (shown) is typical for most of these metals, but t...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
When a typical Arrhenius acid such as hydrochloric acid reacts with a metal or a base, the Arrhenius definitions make it easy to follow the reactions. For example, hydrochloric acid, HCl, reacts with zinc, Zn, to form zinc chloride and hydrogen gas. The negative Cl ions combine with the...
