The chemical formula for arsenite can be written in a couple of ways: AsO33- or AsO2-. These formulas show the different atoms that make up the arsenite ion. Arsenites are also known as salts of arsenous acid, which is another arsenic compound.
What is Arsenite?
Arsenite is a chemical compound that includes arsenic, which is a naturally occurring element found in the Earth's crust. Arsenite is one of many ways arsenic can exist in nature. It's important to know that all arsenites are considered very toxic, meaning they can be harmful to living things if not handled properly.
Arsenite in Water
Sometimes, especially when talking about water found underground (called groundwater), the word "arsenite" might also refer to arsenic trioxide. This is because arsenic trioxide can turn into arsenite ions when it dissolves in water. Scientists who study groundwater chemistry often look for arsenite because it can affect water quality.
An Example of Arsenite
A common example of an arsenite compound is Sodium arsenite. This is a salt that contains the arsenite ion along with sodium.
