Chemistry formula writing and naming

If you are using an electronic pH meter here is some useful information concerning probe care and calibration.

Chemistry formula writing and naming

Phosphate ion PO Pattern 1: For instance, if you know nitrate is NO3-,then nitrite is NO If you know phosphate is PO,then you know phosphite is PO You can also use the prefixes hypo- and per- with the chlorate series.

Hypochlorite is a double whammy: You can also substitute the other halogens for Cl and make additional sets of the series. The -ates with charges less than negative 1 that is, ions with charges of -2, -3, etc. HCO3-is called either the bicarbonate ion or the hydrogen carbonate ion.

These are named hydrogen phosphate and dihydrogen phosphate, respectively. That means you need to see the naming acids rules.

The following periodic table will also come in handy. Working backward from the halogens, or 7A family, the oxidation states are most commonly -1, while the 6A family is -2, and the 5A family is Naming acids is extremely easy if you know your polyatomic ions.

There are three rules to follow: HCl is hydrochloric acid; H2S is hydrosulfuric acid. When you see an acid name beginning with hydro- think: HCN is an exception since it is a polyatomic ion without oxygen, so it is named hydrocyanic acid. If the acid has an -ate polyatomic ion after the H, that makes it an -ic acid.

H2SO4 is sulfuric acid. When the acid has an -ite polyatomic ion after the H, that makes it an -ous acid. H2SO3 is sulfurous acid.How to Name Chemical Compounds.

In this Article: Article Summary Naming Ionic Compounds Naming Polyatomic Compounds Naming Covalent Compounds Community Q&A Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is.

In chemistry, the empirical formula of a chemical is a simple expression of the relative number of each type of atom or ratio of the elements in the compound.

Empirical formulas are the standard for ionic compounds, such as CaCl 2, and for macromolecules, such as SiO empirical formula makes no reference to isomerism, structure, or absolute number of atoms.

6. APPLY CHEMISTRY TO EVERYDAY LIFE: The study of science as a mental exercise is not very useful. Applying science knowledge to practical everyday problems is the main purpose in studying any science; chemistry, physics, biology, or mathematics; for example.
