Tellurium oxoacids are a group of acids that contain the element tellurium bonded to oxygen and hydrogen. These acids are derived from tellurium oxides and typically include compounds like tellurous acid (H2TeO3) and telluric acid (H2TeO4). They are characterized by their ability to donate protons (H+) in aqueous solutions, making them acidic. These oxoacids are important in various chemical reactions and can be used in analytical chemistry. Their properties and behavior are influenced by the oxidation state of tellurium, which can vary in different compounds. Understanding these acids is essential for applications in materials science and environmental chemistry.
