Vanadic acid is a chemical compound with the formula HVO3. The word "vanadic" is pronounced /vəˈnadɪk/ (vuh-NA-dik) in IPA phonetic transcription, with stress on the second syllable. The spelling of this word comes from the element vanadium, which is commonly used in various industrial applications. Vanadium is a transition metal with the symbol V and is named after the Scandinavian goddess Vanadis. Vanadic acid is used in analytical chemistry and in the production of catalysts and pigments.
Vanadic acid is a chemical compound with the formula HVO3 or H2V2O7. It is a strong acid that is formed by dissolving vanadium pentoxide (V2O5) in water. Also known as metavanadic acid, it is an intermediate compound in the production of various vanadium salts.
Vanadic acid is a white solid that can be crystalline or amorphous. It is highly soluble in water and forms a colorless solution. In terms of chemical structure, it exists as a polymeric vanadate ion ([VO3]^-) in aqueous solutions. The acid dissociates into hydrogen ions (H+) and vanadate ions (VO3^-) in water, making it a strong acid capable of donating protons.
Vanadic acid finds applications in various industries, primarily in the field of catalysis and as a starting material for synthesizing other vanadium compounds. It is utilized as a catalyst in several chemical reactions and can also be employed in the production of pigments, ceramics, and as an additive in coatings and pigments. Additionally, vanadic acid has potential uses in battery technology due to its ability to participate in redox reactions.
Due to its strong acid properties and potential chemical reactivity, vanadic acid must be handled with caution. It can irritate and damage the skin, eyes, and respiratory system on contact. Therefore, proper safety measures should be taken when working with or using this compound.

The word "vanadic acid" is derived from the element vanadium, which in turn comes from the Latin word "Vanadis". Vanadis was an alternative name for the Norse goddess Freyja and was given to the element as a nod to the vibrant and colorful compounds it forms. The term "acid" is used to denote its acidic nature due to its ability to form salts when reacting with bases.
