Arsenic acid H3AsO4 - PubChem

WebThe word arsenate is derived from arsenic acid, H 3 AsO 4. This moderately strong acid converts to dihydrogen arsenate ( H. 4 ), depending on pH. The quantitative relationship between these species is defined by the acid dissociation constants: These values are similar to those of the hydrogen phosphates.

WebIt is a colorless (clear) solid with very low solubility in water at room temperature. When it does dissolve appreciably at an elevated temperature, it forms NaH2AsO4 (aq) → Na+ (aq) + H2AsO4– (aq).

Because the reaction favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent. This reaction may be thought of as the formation of hydronium ions: maricopa county k9 unit
