Relating to arsenic compounds where arsenic has a valence of 5, or describing compounds containing the arsenic group.
From arsenic + -ic (chemical suffix for higher valence). This systematic chemical nomenclature distinguishes between arsenic compounds of different oxidation states.
Arsinic acid (H₃AsO₄) is the oxidized form of arsenic, and paradoxically, it's sometimes less toxic than reduced arsenous compounds because it doesn't penetrate cells as easily.
