Because the reaction favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent.

The word arsenate is derived from arsenic acid, H3AsO4. This moderately strong acid converts to dihydrogen arsenate (H 2AsO 4), hydrogen arsenate (HAsO 4), and arsenate (AsO 4), depending on pH. The quantitative relationship between these species is defined by the acid dissociation constants: H3AsO4 + H2O ⇌ H 2AsO 4 + H3O (log K1 = −2.19) H 2AsO 4 + H2O ⇌ HAsO 4 + H3O (log K…
