Selenium oxoacids are a group of acids that contain the element selenium bonded to oxygen and hydrogen. These acids are derived from selenium and include compounds like selenous acid (H2SeO3) and selenic acid (H2SeO4). They are characterized by their ability to donate protons (H+) in solution, making them acidic. These oxoacids play a role in various chemical reactions and can be used in laboratory settings. Their properties and reactivity are similar to those of other oxoacids, such as sulfur oxoacids, due to the presence of oxygen in their structure.
