H2so4 is what type of compound

Other metals may react or dissolve in this acid, but gold will not. Then the sample is added to a mixture of nitric acid and hydrochloric acid. Gold will only dissolve in this mixture. The term "acid test" arose from the California gold rush in the late 's when this combination was used to test for the presence of real gold. It has since come to mean, "tested and approved" in a number of fields.

An acid can be defined in several ways. This is a different type of compound than the others we have seen so far. However, when these molecules are dissolved in water, the chemical bond between the hydrogen atom and the rest of the molecule breaks, leaving a positively-charged hydrogen ion and an anion.

This can be symbolized in a chemical equation:. Organic acids are also an important class of compounds, but will not be discussed here. Since all acids contain hydrogen, the name of an acid is based on the anion that goes with it. These anions can either be monatomic or polyatomic. A binary acid is an acid that consists of hydrogen and one other element. The most common binary acids contain a halogen. The acid name begins with the prefix hydro-.

An oxyacid is an acid that consists of hydrogen, oxygen, and a third element. The third element is usually a nonmetal. The name of the acid is the root of the anion followed by the suffix -ous.

There is no prefix. The name of the acid is the root of the anion followed by the suffix -ic. If you are the author of this article, you do not need to request permission to reproduce figures and diagrams provided correct acknowledgement is given.
