    Solubility Information

    The solubility of boric acid is influenced by the presence of other salts. Lithium and sodium chlorides and mineral acids decrease the solubility, while potassium and rubidium chlorides increase it. Potassium nitrate, potassium sulfate, sodium nitrate and sodium sulfate also increase the solubility. The presence of borax raises the solubility due to the formation of polyborate ions.

    Stability Information

    Boric acid is stable at ordinary temperatures. Upon heating it gradually loses water, changing to metaboric acid HBO₂. On continued heating all water is lost, and the anhydrous oxide B₂O₃ is formed.
